* [Parallel codegen][parcodegen] is now working again, which can substantially

speed up large builds in debug mode; It also gets another ~33% speedup when

bootstrapping on a 4 core machine (using 8 jobs). It's not enabled by default,

std: Stabilize a number of new fs features
This commit stabilizes the following APIs, slating them all to be cherry-picked
into the 1.1 release.
* fs::FileType (and transitively the derived trait implementations)
* fs::Metadata::file_type
* fs::FileType::is_dir
* fs::FileType::is_file
* fs::FileType::is_symlink
* fs::DirEntry::metadata
* fs::DirEntry::file_type
* fs::DirEntry::file_name
* fs::set_permissions
* fs::symlink_metadata
* os::raw::{self, *}
* os::{android, bitrig, linux, ...}::raw::{self, *}
* os::{android, bitrig, linux, ...}::fs::MetadataExt
* os::{android, bitrig, linux, ...}::fs::MetadataExt::as_raw_stat
* os::unix::fs::PermissionsExt
* os::unix::fs::PermissionsExt::mode
* os::unix::fs::PermissionsExt::set_mode
* os::unix::fs::PermissionsExt::from_mode
* os::unix::fs::OpenOptionsExt
* os::unix::fs::OpenOptionsExt::mode
* os::unix::fs::DirEntryExt
* os::unix::fs::DirEntryExt::ino
* os::windows::fs::MetadataExt
* os::windows::fs::MetadataExt::file_attributes
* os::windows::fs::MetadataExt::creation_time
* os::windows::fs::MetadataExt::last_access_time
* os::windows::fs::MetadataExt::last_write_time
* os::windows::fs::MetadataExt::file_size
The `os::unix::fs::Metadata` structure was also removed entirely, moving all of
its associated methods into the `os::unix::fs::MetadataExt` trait instead. The
methods are all marked as `#[stable]` still.
As some minor cleanup, some deprecated and unstable fs apis were also removed:
* File::path
* Metadata::accessed
* Metadata::modified
Features that were explicitly left unstable include:
* fs::WalkDir - the semantics of this were not considered in the recent fs
expansion RFC.
* fs::DirBuilder - it's still not 100% clear if the naming is right here and if
the set of functionality exposed is appropriate.
* fs::canonicalize - the implementation on Windows here is specifically in
question as it always returns a verbatim path. Additionally the Unix
implementation is susceptible to buffer overflows on long paths unfortunately.
* fs::PathExt - as this is just a convenience trait, it is not stabilized at
this time.
* fs::set_file_times - this funciton is still waiting on a time abstraction.

functionality exposed:
|
|
|
|
|
* `DirEntry` now supports optimizations like `file_type` and `metadata` which
|
|
|
|
|
don't incur a syscall on some platforms.
|
|
|
|
|
* A `symlink_metadata` function has been added.
|
|
|
|
|
* The `fs::Metadata` structure now lowers to its OS counterpart, providing
|
|
|
|
|
access to all underlying information.
|
2015-06-25 08:29:09 -05:00
|
|
|
* The compiler now contains extended explanations of many errors. When an error
|
|
|
|
|
with an explanation occurs the compiler suggests using the `--explain` flag
|
|
|
|
|
to read the explanation. Error explanations are also [available online][err-index].
|
2015-06-10 20:59:55 -05:00
|
|
|
* Thanks to multiple [improvements][sk] to [type checking][pre], as
|
|
|
|
|
well as other work, the time to bootstrap the compiler decreased by
|
|
|
|
|
32%.

|
---------
|
|
|
|
|
|
2015-06-25 10:41:48 -05:00
|
|
|
* The [`str::split_whitespace`] method splits a string on unicode
|
2015-06-10 20:59:55 -05:00
|
|
|
whitespace boundaries.
|
|
|
|
|
* On both Windows and Unix, new extension traits provide conversion of
|
|
|
|
|
I/O types to and from the underlying system handles. On Unix, these
|
2015-06-25 10:41:48 -05:00
|
|
|
traits are [`FromRawFd`] and [`AsRawFd`], on Windows `FromRawHandle`
|
2015-06-10 20:59:55 -05:00
|
|
|
and `AsRawHandle`. These are implemented for `File`, `TcpStream`,
|
|
|
|
|
`TcpListener`, and `UpdSocket`. Further implementations for
|
|
|
|
|
`std::process` will be stabilized later.
|
|
|
|
|
* On Unix, [`std::os::unix::symlink`] creates symlinks. On
|
|
|
|
|
Windows, symlinks can be created with
|
|
|
|
|
`std::os::windows::symlink_dir` and
|
|
|
|
|
`std::os::windows::symlink_file`.
|
|
|
|
|
* The `mpsc::Receiver` type can now be converted into an iterator with
|
|
|
|
|
`into_iter` on the [`IntoIterator`] trait.
|
|
|
|
|
* `Ipv4Addr` can be created from `u32` with the `From<u32>`
|
|
|
|
|
implementation of the [`From`] trait.
|
|
|
|
|
* The `Debug` implementation for `RangeFull` [creates output that is
|
|
|
|
|
more consistent with other implementations][rf].
|
|
|
|
|
* [`Debug` is implemented for `File`][file].
|
|
|
|
|
* The `Default` implementation for `Arc` [no longer requires `Sync +
|
|
|
|
|
Send`][arc].
|
|
|
|
|
* [The `Iterator` methods `count`, `nth`, and `last` have been
|
|
|
|
|
overridden for slices to have O(1) performance instead of O(n)][si].
|
|
|
|
|
* Incorrect handling of paths on Windows has been improved in both the
|
|
|
|
|
compiler and the standard library.
|
|
|
|
|
* [`AtomicPtr` gained a `Default` implementation][ap].
|
|
|
|
|
* In accordance with Rust's policy on arithmetic overflow `abs` now
|
|
|
|
|
[panics on overflow when debug assertions are enabled][abs].
|
|
|
|
|
* The [`Cloned`] iterator, which was accidentally left unstable for
|
|
|
|
|
1.0 [has been stabilized][c].
|
|
|
|
|
* The [`Incoming`] iterator, which iterates over incoming TCP
|
|
|
|
|
connections, and which was accidentally unnamable in 1.0, [is now
|
|
|
|
|
properly exported][inc].
|
|
|
|
|
* [`BinaryHeap`] no longer corrupts itself [when functions called by
|
|
|
|
|
`sift_up` or `sift_down` panic][bh].
|
|
|
|
|
* The [`split_off`] method of `LinkedList` [no longer corrupts
|
|
|
|
|
the list in certain scenarios][ll].

|
Misc
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
* Type checking performance [has improved notably][sk] with
|
|
|
|
|
[multiple improvements][pre].
|
|
|
|
|
* The compiler [suggests code changes][ch] for more errors.
|
|
|
|
|
* rustc and it's build system have experimental support for [building
|
|
|
|
|
toolchains against MUSL][m] instead of glibc on Linux.
|
|
|
|
|
* The compiler defines the `target_env` cfg value, which is used for
|
|
|
|
|
distinguishing toolchains that are otherwise for the same
|
|
|
|
|
platform. Presently this is set to `gnu` for common GNU Linux
|
|
|
|
|
targets and for MinGW targets, and `musl` for MUSL Linux targets.
|
|
|
|
|
* The [`cargo rustc`][crc] command invokes a build with custom flags
|
|
|
|
|
to rustc.
|
|
|
|
|
* [Android executables are always position independent][pie].
|
|
|
|
|
* [The `drop_with_repr_extern` lint warns about mixing `repr(C)`
|
|
|
|
|
with `Drop`][drop].

* fs::WalkDir - the semantics of this were not considered in the recent fs
expansion RFC.
* fs::DirBuilder - it's still not 100% clear if the naming is right here and if
the set of functionality exposed is appropriate.
* fs::canonicalize - the implementation on Windows here is specifically in
question as it always returns a verbatim path. Additionally the Unix
implementation is susceptible to buffer overflows on long paths unfortunately.
* fs::PathExt - as this is just a convenience trait, it is not stabilized at
this time.
* fs::set_file_times - this funciton is still waiting on a time abstraction.

|
|
* The vast majority of the standard library is now `#[stable]`. It is
|
|
|
|
|
no longer possible to use unstable features with a stable build of
|
|
|
|
|
the compiler.
|
|
|
|
|
* Many popular crates on [crates.io] now work on the stable release
|
|
|
|
|
channel.
|
|
|
|
|
* Arithmetic on basic integer types now [checks for overflow in debug
|
|
|
|
|
builds][overflow].

--------

2015-04-01 18:40:06 -05:00
|
|
|
|
2015-05-06 15:23:33 -05:00
|
|
|
* Several [restrictions have been added to trait coherence][coh] in
|
|
|
|
|
order to make it easier for upstream authors to change traits
|
2015-05-19 19:34:14 -05:00
|
|
|
without breaking downstream code.
|
2015-05-06 15:23:33 -05:00
|
|
|
* Digits of binary and octal literals are [lexed more eagerly][lex] to
|
|
|
|
|
improve error messages and macro behavior. For example, `0b1234` is
|
|
|
|
|
now lexed as `0b1234` instead of two tokens, `0b1` and `234`.
|
2015-05-17 19:09:11 -05:00
|
|
|
* Trait bounds [are always invariant][inv], eliminating the need for
|
2015-05-06 15:23:33 -05:00
|
|
|
the `PhantomFn` and `MarkerTrait` lang items, which have been
|
|
|
|
|
removed.
|
|
|
|
|
* ["-" is no longer a valid character in crate names][cr], the `extern crate
|
|
|
|
|
"foo" as bar` syntax has been replaced with `extern crate foo as
|
|
|
|
|
bar`, and Cargo now automatically translates "-" in *package* names
|
|
|
|
|
to underscore for the crate name.
|
|
|
|
|
* [Lifetime shadowing is an error][lt].
|
|
|
|
|
* [`Send` no longer implies `'static`][send-rfc].
|
|
|
|
|
* [UFCS now supports trait-less associated paths][moar-ufcs] like
|
|
|
|
|
`MyType::default()`.
|
|
|
|
|
* Primitive types [now have inherent methods][prim-inherent],
|
|
|
|
|
obviating the need for extension traits like `SliceExt`.
|
|
|
|
|
* Methods with `Self: Sized` in their `where` clause are [considered
|
|
|
|
|
object-safe][self-sized], allowing many extension traits like
|
|
|
|
|
`IteratorExt` to be merged into the traits they extended.
|
|
|
|
|
* You can now [refer to associated types][assoc-where] whose
|
|
|
|
|
corresponding trait bounds appear only in a `where` clause.
|
|
|
|
|
* The final bits of [OIBIT landed][oibit-final], meaning that traits
|
|
|
|
|
like `Send` and `Sync` are now library-defined.
|
|
|
|
|
* A [Reflect trait][reflect] was introduced, which means that
|
|
|
|
|
downcasting via the `Any` trait is effectively limited to concrete
|
|
|
|
|
types. This helps retain the potentially-important "parametricity"
|
|
|
|
|
property: generic code cannot behave differently for different type
|
|
|
|
|
arguments except in minor ways.
|
|
|
|
|
* The `unsafe_destructor` feature is now deprecated in favor of the
|
|
|
|
|
[new `dropck`][dropck]. This change is a major reduction in unsafe
|
|
|
|
|
code.

|
|
|
|
2015-05-06 15:23:33 -05:00
|
|
|
* The `thread_local` module [has been renamed to `std::thread`][th].
|
|
|
|
|
* The methods of `IteratorExt` [have been moved to the `Iterator`
|
|
|
|
|
trait itself][ie].
|
|
|
|
|
* Several traits that implement Rust's conventions for type
|
|
|
|
|
conversions, `AsMut`, `AsRef`, `From`, and `Into` have been
|
|
|
|
|
[centralized in the `std::convert` module][con].
|
|
|
|
|
* The `FromError` trait [was removed in favor of `From`][fe].
|
|
|
|
|
* The basic sleep function [has moved to
|
|
|
|
|
`std::thread::sleep_ms`][slp].
|
|
|
|
|
* The `splitn` function now takes an `n` parameter that represents the
|
|
|
|
|
number of items yielded by the returned iterator [instead of the
|
|
|
|
|
number of 'splits'][spl].
|
|
|
|
|
* [On Unix, all file descriptors are `CLOEXEC` by default][clo].
|
|
|
|
|
* [Derived implementations of `PartialOrd` now order enums according
|
|
|
|
|
to their explicitly-assigned discriminants][po].
|
|
|
|
|
* [Methods for searching strings are generic over `Pattern`s][pat],
|
|
|
|
|
implemented presently by `&char`, `&str`, `FnMut(char) -> bool` and
|
|
|
|
|
some others.
|
|
|
|
|
* [In method resolution, object methods are resolved before inherent
|
|
|
|
|
methods][meth].
|
|
|
|
|
* [`String::from_str` has been deprecated in favor of the `From` impl,
|
|
|
|
|
`String::from`][sf].
|
|
|
|
|
* [`io::Error` implements `Sync`][ios].
|
|
|
|
|
* [The `words` method on `&str` has been replaced with
|
|
|
|
|
`split_whitespace`][sw], to avoid answering the tricky question, 'what is
|
|
|
|
|
a word?'
|
|
|
|
|
* The new path and IO modules are complete and `#[stable]`. This
|
|
|
|
|
was the major library focus for this cycle.
|
|
|
|
|
* The path API was [revised][path-normalize] to normalize `.`,
|
|
|
|
|
adjusting the tradeoffs in favor of the most common usage.
|
|
|
|
|
* A large number of remaining APIs in `std` were also stabilized
|
|
|
|
|
during this cycle; about 75% of the non-deprecated API surface
|
|
|
|
|
is now stable.
|
|
|
|
|
* The new [string pattern API][string-pattern] landed, which makes
|
|
|
|
|
the string slice API much more internally consistent and flexible.
|
|
|
|
|
* A new set of [generic conversion traits][conversion] replaced
|
|
|
|
|
many existing ad hoc traits.
|
|
|
|
|
* Generic numeric traits were [completely removed][num-traits]. This
|
|
|
|
|
was made possible thanks to inherent methods for primitive types,
|
|
|
|
|
and the removal gives maximal flexibility for designing a numeric
|
|
|
|
|
hierarchy in the future.
|
|
|
|
|
* The `Fn` traits are now related via [inheritance][fn-inherit]
|
|
|
|
|
and provide ergonomic [blanket implementations][fn-blanket].
|
|
|
|
|
* The `Index` and `IndexMut` traits were changed to
|
|
|
|
|
[take the index by value][index-value], enabling code like
|
|
|
|
|
`hash_map["string"]` to work.
|
|
|
|
|
* `Copy` now [inherits][copy-clone] from `Clone`, meaning that all
|
|
|
|
|
`Copy` data is known to be `Clone` as well.

the `--explain` flag to `rustc`.

* Metadata was tuned, shrinking binaries [by 27%][metadata-shrink].
|
|
|
|
|
* Much headway was made on ecosystem-wide CI, making it possible
|
|
|
|
|
to [compare builds for breakage][ci-compare].

2015-05-18 02:57:58 -05:00
|
|
|
=====================================
|
2015-02-18 19:02:34 -06:00
|
|
|
|
|
|
|
|
* ~1300 changes, numerous bugfixes
|
|
|
|
|
|
|
|
|
|
* Highlights
|
|
|
|
|
|
|
|
|
|
* The various I/O modules were [overhauled][io-rfc] to reduce
|
2015-05-19 19:34:14 -05:00
|
|
|
unnecessary abstractions and provide better interoperation with
|
2015-02-18 19:02:34 -06:00
|
|
|
the underlying platform. The old `io` module remains temporarily
|
|
|
|
|
at `std::old_io`.
|
2015-05-19 19:34:14 -05:00
|
|
|
* The standard library now [participates in feature gating][feat],
|
2015-02-18 19:02:34 -06:00
|
|
|
so use of unstable libraries now requires a `#![feature(...)]`
|
|
|
|
|
attribute. The impact of this change is [described on the
|
|
|
|
|
forum][feat-forum]. [RFC][feat-rfc].
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
|
|
|
|
|
* `for` loops [now operate on the `IntoIterator` trait][into],
|
|
|
|
|
which eliminates the need to call `.iter()`, etc. to iterate
|
|
|
|
|
over collections. There are some new subtleties to remember
|
|
|
|
|
though regarding what sort of iterators various types yield, in
|
|
|
|
|
particular that `for foo in bar { }` yields values from a move
|
|
|
|
|
iterator, destroying the original collection. [RFC][into-rfc].
|
|
|
|
|
* Objects now have [default lifetime bounds][obj], so you don't
|
|
|
|
|
have to write `Box<Trait+'static>` when you don't care about
|
|
|
|
|
storing references. [RFC][obj-rfc].
|
|
|
|
|
* In types that implement `Drop`, [lifetimes must outlive the
|
|
|
|
|
value][drop]. This will soon make it possible to safely
|
|
|
|
|
implement `Drop` for types where `#[unsafe_destructor]` is now
|
|
|
|
|
required. Read the [gorgeous RFC][drop-rfc] for details.
|
|
|
|
|
* The fully qualified <T as Trait>::X syntax lets you set the Self
|
|
|
|
|
type for a trait method or associated type. [RFC][ufcs-rfc].
|
|
|
|
|
* References to types that implement `Deref<U>` now [automatically
|
|
|
|
|
coerce to references][deref] to the dereferenced type `U`,
|
|
|
|
|
e.g. `&T where T: Deref<U>` automatically coerces to `&U`. This
|
|
|
|
|
should eliminate many unsightly uses of `&*`, as when converting
|
|
|
|
|
from references to vectors into references to
|
|
|
|
|
slices. [RFC][deref-rfc].
|
|
|
|
|
* The explicit [closure kind syntax][close] (`|&:|`, `|&mut:|`,
|
|
|
|
|
`|:|`) is obsolete and closure kind is inferred from context.
|
|
|
|
|
* [`Self` is a keyword][Self].
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
|
|
|
|
|
* The `Show` and `String` formatting traits [have been
|
|
|
|
|
renamed][fmt] to `Debug` and `Display` to more clearly reflect
|
|
|
|
|
their related purposes. Automatically getting a string
|
|
|
|
|
conversion to use with `format!("{:?}", something_to_debug)` is
|
|
|
|
|
now written `#[derive(Debug)]`.
|
|
|
|
|
* Abstract [OS-specific string types][osstr], `std::ff::{OsString,
|
|
|
|
|
OsStr}`, provide strings in platform-specific encodings for easier
|
|
|
|
|
interop with system APIs. [RFC][osstr-rfc].
|
2015-02-21 06:14:17 -06:00
|
|
|
* The `boxed::into_raw` and `Box::from_raw` functions [convert
|
2015-02-18 19:02:34 -06:00
|
|
|
between `Box<T>` and `*mut T`][boxraw], a common pattern for
|
|
|
|
|
creating raw pointers.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
|
|
|
|
|
* Certain long error messages of the form 'expected foo found bar'
|
|
|
|
|
are now [split neatly across multiple
|
|
|
|
|
lines][multiline]. Examples in the PR.
|
|
|
|
|
* On Unix Rust can be [uninstalled][un] by running
|
|
|
|
|
`/usr/local/lib/rustlib/uninstall.sh`.
|
|
|
|
|
* The `#[rustc_on_unimplemented]` attribute, requiring the
|
|
|
|
|
'on_unimplemented' feature, lets rustc [display custom error
|
|
|
|
|
messages when a trait is expected to be implemented for a type
|
|
|
|
|
but is not][onun].
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
|
|
|
|
|
* Rust is tested against a [LALR grammar][lalr], which parses
|
|
|
|
|
almost all the Rust files that rustc does.

Version 1.0.0-alpha (January 2015)
|
2015-05-18 02:57:58 -05:00
|
|
|
==================================
|
2015-01-06 01:41:12 -06:00
|
|
|
|
2015-01-06 18:37:38 -06:00
|
|
|
* ~2400 changes, numerous bugfixes
|
2015-01-06 01:41:12 -06:00
|
|
|
|
|
|
|
|
* Highlights
|
|
|
|
|
|
|
|
|
|
* The language itself is considered feature complete for 1.0,
|
2015-01-06 22:53:55 -06:00
|
|
|
though there will be many usability improvements and bugfixes
|
|
|
|
|
before the final release.
|
2015-01-06 01:41:12 -06:00
|
|
|
* Nearly 50% of the public API surface of the standard library has
|
2015-01-06 18:50:54 -06:00
|
|
|
been declared 'stable'. Those interfaces are unlikely to change
|
|
|
|
|
before 1.0.
|
2015-01-06 22:53:55 -06:00
|
|
|
* The long-running debate over integer types has been
|
|
|
|
|
[settled][ints]: Rust will ship with types named `isize` and
|
|
|
|
|
`usize`, rather than `int` and `uint`, for pointer-sized
|
|
|
|
|
integers. Guidelines will be rolled out during the alpha cycle.
|
2015-01-06 01:41:12 -06:00
|
|
|
* Most crates that are not `std` have been moved out of the Rust
|
|
|
|
|
distribution into the Cargo ecosystem so they can evolve
|
|
|
|
|
separately and don't need to be stabilized as quickly, including
|
|
|
|
|
'time', 'getopts', 'num', 'regex', and 'term'.
|
2014-12-02 08:20:48 -06:00
|
|
|
* Documentation continues to be expanded with more API coverage, more
|
|
|
|
|
examples, and more in-depth explanations. The guides have been
|
|
|
|
|
consolidated into [The Rust Programming Language][trpl].
|
2015-01-09 01:25:42 -06:00
|
|
|
* "[Rust By Example][rbe]" is now maintained by the Rust team.
|
2015-01-06 01:41:12 -06:00
|
|
|
* All official Rust binary installers now come with [Cargo], the
|
|
|
|
|
Rust package manager.
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
|
|
|
|
|
* Closures have been [completely redesigned][unboxed] to be
|
|
|
|
|
implemented in terms of traits, can now be used as generic type
|
|
|
|
|
bounds and thus monomorphized and inlined, or via an opaque
|
|
|
|
|
pointer (boxed) as in the old system. The new system is often
|
|
|
|
|
referred to as 'unboxed' closures.
|
2015-01-06 06:19:01 -06:00
|
|
|
* Traits now support [associated types][assoc], allowing families
|
|
|
|
|
of related types to be defined together and used generically in
|
|
|
|
|
powerful ways.
|
2015-01-06 01:41:12 -06:00
|
|
|
* Enum variants are [namespaced by their type names][enum].
|
|
|
|
|
* [`where` clauses][where] provide a more versatile and attractive
|
|
|
|
|
syntax for specifying generic bounds, though the previous syntax
|
|
|
|
|
remains valid.
|
2015-01-06 06:19:01 -06:00
|
|
|
* Rust again picks a [fallback][fb] (either i32 or f64) for uninferred
|
2015-01-06 01:41:12 -06:00
|
|
|
numeric types.
|
|
|
|
|
* Rust [no longer has a runtime][rt] of any description, and only
|
|
|
|
|
supports OS threads, not green threads.
|
|
|
|
|
* At long last, Rust has been overhauled for 'dynamically-sized
|
|
|
|
|
types' ([DST]), which integrates 'fat pointers' (object types,
|
|
|
|
|
arrays, and `str`) more deeply into the type system, making it
|
|
|
|
|
more consistent.
|
|
|
|
|
* Rust now has a general [range syntax][range], `i..j`, `i..`, and
|
|
|
|
|
`..j` that produce range types and which, when combined with the
|
2015-01-06 06:19:01 -06:00
|
|
|
`Index` operator and multidispatch, leads to a convenient slice
|
2015-01-06 01:41:12 -06:00
|
|
|
notation, `[i..j]`.
|
|
|
|
|
* The new range syntax revealed an ambiguity in the fixed-length
|
|
|
|
|
array syntax, so now fixed length arrays [are written `[T;
|
|
|
|
|
N]`][arrays].
|
|
|
|
|
* The `Copy` trait is no longer implemented automatically. Unsafe
|
|
|
|
|
pointers no longer implement `Sync` and `Send` so types
|
|
|
|
|
containing them don't automatically either. `Sync` and `Send`
|
|
|
|
|
are now 'unsafe traits' so one can "forcibly" implement them via
|
|
|
|
|
`unsafe impl` if a type confirms to the requirements for them
|
|
|
|
|
even though the internals do not (e.g. structs containing unsafe
|
|
|
|
|
pointers like `Arc`). These changes are intended to prevent some
|
|
|
|
|
footguns and are collectively known as [opt-in built-in
|
2015-01-07 00:16:34 -06:00
|
|
|
traits][oibit] (though `Sync` and `Send` will soon become pure
|
2015-01-06 01:41:12 -06:00
|
|
|
library types unknown to the compiler).
|
|
|
|
|
* Operator traits now take their operands [by value][ops], and
|
|
|
|
|
comparison traits can use multidispatch to compare one type
|
|
|
|
|
against multiple other types, allowing e.g. `String` to be
|
|
|
|
|
compared with `&str`.
|
|
|
|
|
* `if let` and `while let` are no longer feature-gated.
|
|
|
|
|
* Rust has adopted a more [uniform syntax for escaping unicode
|
|
|
|
|
characters][unicode].
|
|
|
|
|
* `macro_rules!` [has been declared stable][mac]. Though it is a
|
|
|
|
|
flawed system it is sufficiently popular that it must be usable
|
2015-01-06 18:44:17 -06:00
|
|
|
for 1.0. Effort has gone into [future-proofing][mac-future] it
|
|
|
|
|
in ways that will allow other macro systems to be developed in
|
|
|
|
|
parallel, and won't otherwise impact the evolution of the
|
|
|
|
|
language.
|
2015-01-06 01:41:12 -06:00
|
|
|
* The prelude has been [pared back significantly][prelude] such
|
|
|
|
|
that it is the minimum necessary to support the most pervasive
|
|
|
|
|
code patterns, and through [generalized where clauses][where]
|
|
|
|
|
many of the prelude extension traits have been consolidated.
|
|
|
|
|
* Rust's rudimentary reflection [has been removed][refl], as it
|
|
|
|
|
incurred too much code generation for little benefit.
|
|
|
|
|
* [Struct variants][structvars] are no longer feature-gated.
|
|
|
|
|
* Trait bounds can be [polymorphic over lifetimes][hrtb]. Also
|
|
|
|
|
known as 'higher-ranked trait bounds', this crucially allows
|
|
|
|
|
unboxed closures to work.
|
|
|
|
|
* Macros invocations surrounded by parens or square brackets and
|
|
|
|
|
not terminated by a semicolon are [parsed as
|
|
|
|
|
expressions][macros], which makes expressions like `vec![1i32,
|
|
|
|
|
2, 3].len()` work as expected.
|
2015-01-06 06:19:01 -06:00
|
|
|
* Trait objects now implement their traits automatically, and
|
|
|
|
|
traits that can be coerced to objects now must be [object
|
|
|
|
|
safe][objsafe].
|
2015-01-06 01:41:12 -06:00
|
|
|
* Automatically deriving traits is now done with `#[derive(...)]`
|
|
|
|
|
not `#[deriving(...)]` for [consistency with other naming
|
|
|
|
|
conventions][derive].
|
2015-01-06 06:19:01 -06:00
|
|
|
* Importing the containing module or enum at the same time as
|
|
|
|
|
items or variants they contain is [now done with `self` instead
|
|
|
|
|
of `mod`][self], as in use `foo::{self, bar}`
|
2015-01-06 18:37:38 -06:00
|
|
|
* Glob imports are no longer feature-gated.
|
2015-01-06 18:44:17 -06:00
|
|
|
* The `box` operator and `box` patterns have been feature-gated
|
|
|
|
|
pending a redesign. For now unique boxes should be allocated
|
|
|
|
|
like other containers, with `Box::new`.
|
2015-01-06 01:41:12 -06:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
|
|
|
|
|
* A [series][coll1] of [efforts][coll2] to establish
|
|
|
|
|
[conventions][coll3] for collections types has resulted in API
|
|
|
|
|
improvements throughout the standard library.
|
|
|
|
|
* New [APIs for error handling][err] provide ergonomic interop
|
|
|
|
|
between error types, and [new conventions][err-conv] describe
|
|
|
|
|
more clearly the recommended error handling strategies in Rust.
|
|
|
|
|
* The `fail!` macro has been renamed to [`panic!`][panic] so that
|
|
|
|
|
it is easier to discuss failure in the context of error handling
|
|
|
|
|
without making clarifications as to whether you are referring to
|
|
|
|
|
the 'fail' macro or failure more generally.
|
2015-01-06 06:19:01 -06:00
|
|
|
* On Linux, `OsRng` prefers the new, more reliable `getrandom`
|
2015-01-06 01:41:12 -06:00
|
|
|
syscall when available.
|
|
|
|
|
* The 'serialize' crate has been renamed 'rustc-serialize' and
|
|
|
|
|
moved out of the distribution to Cargo. Although it is widely
|
2015-05-19 19:34:14 -05:00
|
|
|
used now, it is expected to be superseded in the near future.
|
2015-01-06 01:41:12 -06:00
|
|
|
* The `Show` formatter, typically implemented with
|
|
|
|
|
`#[derive(Show)]` is [now requested with the `{:?}`
|
|
|
|
|
specifier][show] and is intended for use by all types, for uses
|
|
|
|
|
such as `println!` debugging. The new `String` formatter must be
|
|
|
|
|
implemented by hand, uses the `{}` specifier, and is intended
|
|
|
|
|
for full-fidelity conversions of things that can logically be
|
|
|
|
|
represented as strings.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
|
|
|
|
|
* [Flexible target specification][flex] allows rustc's code
|
|
|
|
|
generation to be configured to support otherwise-unsupported
|
|
|
|
|
platforms.
|
|
|
|
|
* Rust comes with rust-gdb and rust-lldb scripts that launch their
|
|
|
|
|
respective debuggers with Rust-appropriate pretty-printing.
|
|
|
|
|
* The Windows installation of Rust is distributed with the the
|
|
|
|
|
MinGW components currently required to link binaries on that
|
|
|
|
|
platform.
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
|
|
|
|
|
* Nullable enum optimizations have been extended to more types so
|
|
|
|
|
that e.g. `Option<Vec<T>>` and `Option<String>` take up no more
|
|
|
|
|
space than the inner types themselves.
|
|
|
|
|
* Work has begun on supporting AArch64.

|
|
|
|
|
|
|
|
|
|
* The introductory documentation (now called The Rust Guide) has
|
|
|
|
|
been completely rewritten, as have a number of supplementary
|
|
|
|
|
guides.
|
2014-10-06 19:30:30 -05:00
|
|
|
* Rust's package manager, Cargo, continues to improve and is
|
|
|
|
|
sometimes considered to be quite awesome.
|
2014-10-02 17:54:43 -05:00
|
|
|
* Many API's in `std` have been reviewed and updated for
|
|
|
|
|
consistency with the in-development Rust coding
|
|
|
|
|
guidelines. The standard library documentation tracks
|
|
|
|
|
stabilization progress.
|
|
|
|
|
* Minor libraries have been moved out-of-tree to the rust-lang org
|
|
|
|
|
on GitHub: uuid, semver, glob, num, hexfloat, fourcc. They can
|
|
|
|
|
be installed with Cargo.
|
|
|
|
|
* Lifetime elision allows lifetime annotations to be left off of
|
|
|
|
|
function declarations in many common scenarios.
|
|
|
|
|
* Rust now works on 64-bit Windows.
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* Indexing can be overloaded with the `Index` and `IndexMut`
|
|
|
|
|
traits.
|
|
|
|
|
* The `if let` construct takes a branch only if the `let` pattern
|
|
|
|
|
matches, currently behind the 'if_let' feature gate.
|
2014-10-06 14:07:28 -05:00
|
|
|
* 'where clauses', a more flexible syntax for specifying trait
|
|
|
|
|
bounds that is more aesthetic, have been added for traits and
|
|
|
|
|
free functions. Where clauses will in the future make it
|
|
|
|
|
possible to constrain associated types, which would be
|
|
|
|
|
impossible with the existing syntax.
|
|
|
|
|
* A new slicing syntax (e.g. `[0..4]`) has been introduced behind
|
|
|
|
|
the 'slicing_syntax' feature gate, and can be overloaded with
|
2014-10-06 19:30:30 -05:00
|
|
|
the `Slice` or `SliceMut` traits.
|
2014-10-06 14:07:28 -05:00
|
|
|
* The syntax for matching of sub-slices has been changed to use a
|
|
|
|
|
postfix `..` instead of prefix (.e.g. `[a, b, c..]`), for
|
|
|
|
|
consistency with other uses of `..` and to future-proof
|
|
|
|
|
potential additional uses of the syntax.
|
|
|
|
|
* The syntax for matching inclusive ranges in patterns has changed
|
|
|
|
|
from `0..3` to `0...4` to be consistent with the exclusive range
|
|
|
|
|
syntax for slicing.
|
|
|
|
|
* Matching of sub-slices in non-tail positions (e.g. `[a.., b,
|
|
|
|
|
c]`) has been put behind the 'advanced_slice_patterns' feature
|
|
|
|
|
gate and may be removed in the future.
|
|
|
|
|
* Components of tuples and tuple structs can be extracted using
|
|
|
|
|
the `value.0` syntax, currently behind the `tuple_indexing`
|
|
|
|
|
feature gate.
|
2014-10-02 17:54:43 -05:00
|
|
|
* The `#[crate_id]` attribute is no longer supported; versioning
|
|
|
|
|
is handled by the package manager.
|
2014-10-06 14:07:28 -05:00
|
|
|
* Renaming crate imports are now written `extern crate foo as bar`
|
|
|
|
|
instead of `extern crate bar = foo`.
|
|
|
|
|
* Renaming use statements are now written `use foo as bar` instead
|
|
|
|
|
of `use bar = foo`.
|
|
|
|
|
* `let` and `match` bindings and argument names in macros are now
|
|
|
|
|
hygienic.
|
2014-10-02 17:54:43 -05:00
|
|
|
* The new, more efficient, closure types ('unboxed closures') have
|
|
|
|
|
been added under a feature gate, 'unboxed_closures'. These will
|
|
|
|
|
soon replace the existing closure types, once higher-ranked
|
|
|
|
|
trait lifetimes are added to the language.
|
2014-10-06 14:07:28 -05:00
|
|
|
* `move` has been added as a keyword, for indicating closures
|
|
|
|
|
that capture by value.
|
|
|
|
|
* Mutation and assignment is no longer allowed in pattern guards.
|
|
|
|
|
* Generic structs and enums can now have trait bounds.
|
2014-10-02 17:54:43 -05:00
|
|
|
* The `Share` trait is now called `Sync` to free up the term
|
|
|
|
|
'shared' to refer to 'shared reference' (the default reference
|
|
|
|
|
type.
|
|
|
|
|
* Dynamically-sized types have been mostly implemented,
|
|
|
|
|
unifying the behavior of fat-pointer types with the rest of the
|
|
|
|
|
type system.
|
|
|
|
|
* As part of dynamically-sized types, the `Sized` trait has been
|
|
|
|
|
introduced, which qualifying types implement by default, and
|
|
|
|
|
which type parameters expect by default. To specify that a type
|
2014-10-06 14:07:28 -05:00
|
|
|
parameter does not need to be sized, write `<Sized? T>`. Most
|
2014-10-02 17:54:43 -05:00
|
|
|
types are `Sized`, notable exceptions being unsized arrays
|
|
|
|
|
(`[T]`) and trait types.
|
2014-10-06 14:07:28 -05:00
|
|
|
* Closures can return `!`, as in `|| -> !` or `proc() -> !`.
|
|
|
|
|
* Lifetime bounds can now be applied to type parameters and object
|
|
|
|
|
types.
|
|
|
|
|
* The old, reference counted GC type, `Gc<T>` which was once
|
|
|
|
|
denoted by the `@` sigil, has finally been removed. GC will be
|
|
|
|
|
revisited in the future.
|
2014-10-02 17:54:43 -05:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* Library documentation has been improved for a number of modules.
|
|
|
|
|
* Bit-vectors, collections::bitv has been modernized.
|
|
|
|
|
* The url crate is deprecated in favor of
|
|
|
|
|
http://github.com/servo/rust-url, which can be installed with
|
|
|
|
|
Cargo.
|
2014-10-06 14:07:28 -05:00
|
|
|
* Most I/O stream types can be cloned and subsequently closed from
|
|
|
|
|
a different thread.
|
2014-10-02 17:54:43 -05:00
|
|
|
* A `std::time::Duration` type has been added for use in I/O
|
|
|
|
|
methods that rely on timers, as well as in the 'time' crate's
|
|
|
|
|
`Timespec` arithmetic.
|
2014-10-06 14:07:28 -05:00
|
|
|
* The runtime I/O abstraction layer that enabled the green thread
|
|
|
|
|
scheduler to do non-thread-blocking I/O has been removed, along
|
|
|
|
|
with the libuv-based implementation employed by the green thread
|
|
|
|
|
scheduler. This will greatly simplify the future I/O work.
|
|
|
|
|
* `collections::btree` has been rewritten to have a more
|
|
|
|
|
idiomatic and efficient design.
|
2014-10-02 17:54:43 -05:00
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* rustdoc output now indicates the stability levels of API's.
|
|
|
|
|
* The `--crate-name` flag can specify the name of the crate
|
|
|
|
|
being compiled, like `#[crate_name]`.
|
2014-10-06 14:07:28 -05:00
|
|
|
* The `-C metadata` specifies additional metadata to hash into
|
2014-10-02 17:54:43 -05:00
|
|
|
symbol names, and `-C extra-filename` specifies additional
|
2014-10-06 14:07:28 -05:00
|
|
|
information to put into the output filename, for use by the
|
|
|
|
|
package manager for versioning.
|
2014-10-02 17:54:43 -05:00
|
|
|
* debug info generation has continued to improve and should be
|
|
|
|
|
more reliable under both gdb and lldb.
|
|
|
|
|
* rustc has experimental support for compiling in parallel
|
|
|
|
|
using the `-C codegen-units` flag.
|
|
|
|
|
* rustc no longer encodes rpath information into binaries by
|
|
|
|
|
default.
|
|
|
|
|
|
|
|
|
|
* Misc
|
|
|
|
|
* Stack usage has been optimized with LLVM lifetime annotations.
|
|
|
|
|
* Official Rust binaries on Linux are more compatible with older
|
|
|
|
|
kernels and distributions, built on CentOS 5.10.

==========================
|
2014-06-27 14:46:42 -05:00
|
|
|
|
|
|
|
|
* ~1700 changes, numerous bugfixes
|
|
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* ~[T] has been removed from the language. This type is superseded by
|
|
|
|
|
the Vec<T> type.
|
|
|
|
|
* ~str has been removed from the language. This type is superseded by
|
|
|
|
|
the String type.
|
|
|
|
|
* ~T has been removed from the language. This type is superseded by the
|
|
|
|
|
Box<T> type.
|
|
|
|
|
* @T has been removed from the language. This type is superseded by the
|
|
|
|
|
standard library's std::gc::Gc<T> type.
|
|
|
|
|
* Struct fields are now all private by default.
|
|
|
|
|
* Vector indices and shift amounts are both required to be a `uint`
|
|
|
|
|
instead of any integral type.
|
|
|
|
|
* Byte character, byte string, and raw byte string literals are now all
|
|
|
|
|
supported by prefixing the normal literal with a `b`.
|
|
|
|
|
* Multiple ABIs are no longer allowed in an ABI string
|
|
|
|
|
* The syntax for lifetimes on closures/procedures has been tweaked
|
|
|
|
|
slightly: `<'a>|A, B|: 'b + K -> T`
|
|
|
|
|
* Floating point modulus has been removed from the language; however it
|
|
|
|
|
is still provided by a library implementation.
|
|
|
|
|
* Private enum variants are now disallowed.
|
|
|
|
|
* The `priv` keyword has been removed from the language.
|
|
|
|
|
* A closure can no longer be invoked through a &-pointer.
|
|
|
|
|
* The `use foo, bar, baz;` syntax has been removed from the language.
|
|
|
|
|
* The transmute intrinsic no longer works on type parameters.
|
|
|
|
|
* Statics now allow blocks/items in their definition.
|
|
|
|
|
* Trait bounds are separated from objects with + instead of : now.
|
|
|
|
|
* Objects can no longer be read while they are mutably borrowed.
|
|
|
|
|
* The address of a static is now marked as insignificant unless the
|
|
|
|
|
#[inline(never)] attribute is placed it.
|
|
|
|
|
* The #[unsafe_destructor] attribute is now behind a feature gate.
|
|
|
|
|
* Struct literals are no longer allowed in ambiguous positions such as
|
|
|
|
|
if, while, match, and for..in.
|
|
|
|
|
* Declaration of lang items and intrinsics are now feature-gated by
|
|
|
|
|
default.
|
|
|
|
|
* Integral literals no longer default to `int`, and floating point
|
|
|
|
|
literals no longer default to `f64`. Literals must be suffixed with an
|
|
|
|
|
appropriate type if inference cannot determine the type of the
|
|
|
|
|
literal.
|
|
|
|
|
* The Box<T> type is no longer implicitly borrowed to &mut T.
|
|
|
|
|
* Procedures are now required to not capture borrowed references.
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* The standard library is now a "facade" over a number of underlying
|
|
|
|
|
libraries. This means that development on the standard library should
|
|
|
|
|
be speeder due to smaller crates, as well as a clearer line between
|
|
|
|
|
all dependencies.
|
|
|
|
|
* A new library, libcore, lives under the standard library's facade
|
|
|
|
|
which is Rust's "0-assumption" library, suitable for embedded and
|
|
|
|
|
kernel development for example.
|
|
|
|
|
* A regex crate has been added to the standard distribution. This crate
|
|
|
|
|
includes statically compiled regular expressions.
|
|
|
|
|
* The unwrap/unwrap_err methods on Result require a Show bound for
|
|
|
|
|
better error messages.
|
|
|
|
|
* The return types of the std::comm primitives have been centralized
|
|
|
|
|
around the Result type.
|
|
|
|
|
* A number of I/O primitives have gained the ability to time out their
|
|
|
|
|
operations.
|
|
|
|
|
* A number of I/O primitives have gained the ability to close their
|
|
|
|
|
reading/writing halves to cancel pending operations.
|
|
|
|
|
* Reverse iterator methods have been removed in favor of `rev()` on
|
|
|
|
|
their forward-iteration counterparts.
|
|
|
|
|
* A bitflags! macro has been added to enable easy interop with C and
|
|
|
|
|
management of bit flags.
|
|
|
|
|
* A debug_assert! macro is now provided which is disabled when
|
|
|
|
|
`--cfg ndebug` is passed to the compiler.
|
|
|
|
|
* A graphviz crate has been added for creating .dot files.
|
|
|
|
|
* The std::cast module has been migrated into std::mem.
|
|
|
|
|
* The std::local_data api has been migrated from freestanding functions
|
|
|
|
|
to being based on methods.
|
|
|
|
|
* The Pod trait has been renamed to Copy.
|
|
|
|
|
* jemalloc has been added as the default allocator for types.
|
|
|
|
|
* The API for allocating memory has been changed to use proper alignment
|
|
|
|
|
and sized deallocation
|
|
|
|
|
* Connecting a TcpStream or binding a TcpListener is now based on a
|
|
|
|
|
string address and a u16 port. This allows connecting to a hostname as
|
|
|
|
|
opposed to an IP.
|
|
|
|
|
* The Reader trait now contains a core method, read_at_least(), which
|
|
|
|
|
correctly handles many repeated 0-length reads.
|
|
|
|
|
* The process-spawning API is now centered around a builder-style
|
|
|
|
|
Command struct.
|
|
|
|
|
* The :? printing qualifier has been moved from the standard library to
|
|
|
|
|
an external libdebug crate.
|
|
|
|
|
* Eq/Ord have been renamed to PartialEq/PartialOrd. TotalEq/TotalOrd
|
|
|
|
|
have been renamed to Eq/Ord.
|
|
|
|
|
* The select/plural methods have been removed from format!. The escapes
|
|
|
|
|
for { and } have also changed from \{ and \} to {{ and }},
|
|
|
|
|
respectively.
|
|
|
|
|
* The TaskBuilder API has been re-worked to be a true builder, and
|
|
|
|
|
extension traits for spawning native/green tasks have been added.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* All breaking changes to the language or libraries now have their
|
|
|
|
|
commit message annotated with `[breaking-change]` to allow for easy
|
|
|
|
|
discovery of breaking changes.
|
|
|
|
|
* The compiler will now try to suggest how to annotate lifetimes if a
|
|
|
|
|
lifetime-related error occurs.
|
|
|
|
|
* Debug info continues to be improved greatly with general bug fixes and
|
|
|
|
|
better support for situations like link time optimization (LTO).
|
|
|
|
|
* Usage of syntax extensions when cross-compiling has been fixed.
|
|
|
|
|
* Functionality equivalent to GCC & Clang's -ffunction-sections,
|
|
|
|
|
-fdata-sections and --gc-sections has been enabled by default
|
|
|
|
|
* The compiler is now stricter about where it will load module files
|
|
|
|
|
from when a module is declared via `mod foo;`.
|
|
|
|
|
* The #[phase(syntax)] attribute has been renamed to #[phase(plugin)].
|
|
|
|
|
Syntax extensions are now discovered via a "plugin registrar" type
|
|
|
|
|
which will be extended in the future to other various plugins.
|
|
|
|
|
* Lints have been restructured to allow for dynamically loadable lints.
|
|
|
|
|
* A number of rustdoc improvements:
|
|
|
|
|
* The HTML output has been visually redesigned.
|
|
|
|
|
* Markdown is now powered by hoedown instead of sundown.
|
|
|
|
|
* Searching heuristics have been greatly improved.
|
|
|
|
|
* The search index has been reduced in size by a great amount.
|
|
|
|
|
* Cross-crate documentation via `pub use` has been greatly improved.
|
|
|
|
|
* Primitive types are now hyperlinked and documented.
|
|
|
|
|
* Documentation has been moved from static.rust-lang.org/doc to
|
|
|
|
|
doc.rust-lang.org
|
|
|
|
|
* A new sandbox, play.rust-lang.org, is available for running and
|
|
|
|
|
sharing rust code examples on-line.
|
|
|
|
|
* Unused attributes are now more robustly warned about.
|
|
|
|
|
* The dead_code lint now warns about unused struct fields.
|
|
|
|
|
* Cross-compiling to iOS is now supported.
|
|
|
|
|
* Cross-compiling to mipsel is now supported.
|
|
|
|
|
* Stability attributes are now inherited by default and no longer apply
|
|
|
|
|
to intra-crate usage, only inter-crate usage.
|
|
|
|
|
* Error message related to non-exhaustive match expressions have been
|
|
|
|
|
greatly improved.

|
|
|
|
|
see #3511 and #11585 for more information.
|
|
|
|
|
* Cross-crate syntax extensions are now possible, but feature gated. See
|
|
|
|
|
#11151 for more information. This includes both `macro_rules!` macros as
|
|
|
|
|
well as syntax extensions such as `format!`.
|
|
|
|
|
* New lint modes have been added, and older ones have been turned on to be
|
|
|
|
|
warn-by-default.
|
|
|

|
|
|
|
|

|
2014-03-28 19:08:32 -05:00
|
|
|
* Unsafe functions can no longer be coerced to closures.
|
|
|
|

|
2014-04-01 06:55:09 -05:00
|
|
|
* The `#[simd]` attribute is now behind a feature gate.
|
2014-03-28 19:08:32 -05:00
|
|
|
* Visibility is no longer allowed on `extern crate` statements, and
|
|
|
|
|
unnecessary visibility (`priv`) is no longer allowed on `use` statements.
|
|
|
|
|
* Trailing commas are now allowed in argument lists and tuple patterns.
|
|
|
|
|
* The `do` keyword has been removed, it is now a reserved keyword.
|
|
|
|
|
* Default type parameters have been implemented, but are feature gated.
|
|
|
|
|
* Borrowed variables through captures in closures are now considered soundly.

|
|
|
|
|

|
`DerefMut` traits.
|
|
|
|
|
* `~Trait` and `proc` no longer have `Send` bounds by default.
|
|
|
|
|
* Partial type hints are now supported with the `_` type marker.
|
|
|
|
|
* An `Unsafe` type was introduced for interior mutability. It is now
|
|
|
|
|
considered undefined to transmute from `&T` to `&mut T` without using the
|
|
|
|
|
`Unsafe` type.
|
|
|
|
|
* The #[linkage] attribute was implemented for extern statics/functions.
|
|
|
|

|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* The `libextra` library has been removed. It has now been decomposed into
|
|
|
|
|
component libraries with smaller and more focused nuggets of
|
|
|
|
|
functionality. The full list of libraries can be found on the
|
|
|
|
|
documentation index page.
|
|
|
|
|
* std: `std::condition` has been removed. All I/O errors are now propagated
|
|
|
|
|
through the `Result` type. In order to assist with error handling, a
|
2014-05-01 20:02:11 -05:00
|
|
|
`try!` macro for unwrapping errors with an early return and a lint for
|
2014-03-28 19:08:32 -05:00
|
|
|
unused results has been added. See #12039 for more information.
|
|
|
|
|
* std: The `vec` module has been renamed to `slice`.
|
|
|
|
|
* std: A new vector type, `Vec<T>`, has been added in preparation for DST.
|
|
|
|
|
This will become the only growable vector in the future.
|
|
|
|
|
* std: `std::io` now has more public-reexports. Types such as `BufferedReader`
|
|
|
|
|
are now found at `std::io::BufferedReader` instead of
|
|
|
|
|
`std::io::buffered::BufferedReader`.
|
|
|
|
|
* std: `print` and `println` are no longer in the prelude, the `print!` and
|
|
|
|
|
`println!` macros are intended to be used instead.
|
|
|
|
|
* std: `Rc` now has a `Weak` pointer for breaking cycles, and it no longer
|
|
|
|
|
attempts to statically prevent cycles.
|
|
|
|
|
* std: The standard distribution is adopting the policy of pushing failure
|
|
|
|
|
to the user rather than failing in libraries. Many functions (such as
|
|
|
|
|
`slice::last()`) now return `Option<T>` instead of `T` + failing.
|
|
|
|
|
* std: `fmt::Default` has been renamed to `fmt::Show`, and it now has a new
|
|
|
|
|
deriving mode: `#[deriving(Show)]`.
|
|
|
|
|
* std: `ToStr` is now implemented for all types implementing `Show`.
|
|
|
|
|
* std: The formatting trait methods now take `&self` instead of `&T`
|
|
|
|
|
* std: The `invert()` method on iterators has been renamed to `rev()`
|
|
|
|
|
* std: `std::num` has seen a reduction in the genericity of its traits,
|
|
|
|
|
consolidating functionality into a few core traits.
|
|
|
|
|
* std: Backtraces are now printed on task failure if the environment
|
|
|
|
|
variable `RUST_BACKTRACE` is present.
|
|
|
|
|
* std: Naming conventions for iterators have been standardized. More details
|
|
|
|
|
can be found on the wiki's style guide.
|
|
|
|
|
* std: `eof()` has been removed from the `Reader` trait. Specific types may
|
|
|
|
|
still implement the function.
|
|
|
|
|
* std: Networking types are now cloneable to allow simultaneous reads/writes.
|
|
|
|
|
* std: `assert_approx_eq!` has been removed
|
|
|
|
|
* std: The `e` and `E` formatting specifiers for floats have been added to
|
|
|
|
|
print them in exponential notation.
|
|
|
|
|
* std: The `Times` trait has been removed
|
|
|
|
|
* std: Indications of variance and opting out of builtin bounds is done
|
|
|
|
|
through marker types in `std::kinds::marker` now
|

|
* std: `hash` has been rewritten, `IterBytes` has been removed, and
|
|
|
|
|
`#[deriving(Hash)]` is now possible.
|
|
|
|

|
|
|
|
|
* std: `Chan` and `Port` were renamed to `Sender` and `Receiver`.
|

* std: A new synchronous channel type has been implemented.
|
|
|
|
|
* std: A `select!` macro is now provided for selecting over `Receiver`s.

|
|
|
|
* std: `hashmap` and `trie` have been moved to `libcollections`
|
|
|
|
|
* std: `run` has been rolled into `io::process`
|
|
|
|

|
|
|
|
|
* std: `rand` has moved to `librand`.
|
|
|
|
|

|
|
|
|
|
* collections: `HashMap` has been rewritten for higher performance and less
|
|
|
|
|
memory usage.
|
|
|
|
|
* native: The default runtime is now `libnative`. If `libgreen` is desired,
|
|
|
|
|
it can be booted manually. The runtime guide has more information and
|
|
|
|
|
examples.
|
|
|
|
|
* native: All I/O functionality except signals has been implemented.
|
|
|
|
|
* green: Task spawning with `libgreen` has been optimized with stack caching
|
|
|
|
|
and various trimming of code.
|
|
|
|
|
* green: Tasks spawned by `libgreen` now have an unmapped guard page.
|
|
|
|
|
* sync: The `extra::sync` module has been updated to modern rust (and moved
|
|
|
|
|
to the `sync` library), tweaking and improving various interfaces while
|
|
|
|
|
dropping redundant functionality.
|
|
|
|
|
* sync: A new `Barrier` type has been added to the `sync` library.
|
|
|
|
|
* sync: An efficient mutex for native and green tasks has been implemented.
|
|
|
|
|
* serialize: The `base64` module has seen some improvement. It treats
|
|
|
|
|
newlines better, has non-string error values, and has seen general
|
|
|
|
|
cleanup.
|
|
|
|
|
* fourcc: A `fourcc!` macro was introduced
|
|
|
|
|

|
hexadecimal literal.
|
|
|
|
|
|
|
|
|
|
* Tooling
|
|
|
|
|
* `rustpkg` has been deprecated and removed from the main repository. Its
|
|
|
|
|
replacement, `cargo`, is under development.
|
2014-04-01 06:55:09 -05:00
|
|
|
* Nightly builds of rust are now available
|
2014-03-28 19:08:32 -05:00
|
|
|
* The memory usage of rustc has been improved many times throughout this
|
|
|
|
|
release cycle.
|
|
|
|
|
* The build process supports disabling rpath support for the rustc binary
|
|
|
|
|
itself.
|
|
|
|
|
* Code generation has improved in some cases, giving more information to the
|
|
|
|
|
LLVM optimization passes to enable more extensive optimizations.
|
|
|
|
|
* Debuginfo compatibility with lldb on OSX has been restored.
|
|
|
|
|
* The master branch is now gated on an android bot, making building for
|
|
|
|
|
android much more reliable.
|
|
|
|
|
* Output flags have been centralized into one `--emit` flag.
|
|
|
|
|
* Crate type flags have been centralized into one `--crate-type` flag.
|
|
|
|
|

|
|
|
|
|
* Linking against outdated crates now has improved error messages.
|
|
|
|
|
* Error messages with lifetimes will often suggest how to annotate the
|
|
|
|
|
function to fix the error.
|
|
|
|
|
* Many more types are documented in the standard library, and new guides
|
|
|
|
|
were written.
|
2014-04-01 06:55:09 -05:00
|
|
|
* Many `rustdoc` improvements:
|
|
|
|
|
* code blocks are syntax highlighted.
|
|
|
|
|
* render standalone markdown files.
|
|
|
|
|
* the --test flag tests all code blocks by default.
|
|
|
|
|
* exported macros are displayed.
|
|
|
|
|
* reexported types have their documentation inlined at the location of the
|
|
|
|
|
first reexport.
|
|
|
|
|
* search works across crates that have been rendered to the same output
|
|
|
|
|
directory.

==========================
|
2013-10-16 21:23:12 -05:00
|
|
|
|
2014-01-06 16:50:25 -06:00
|
|
|
* ~1800 changes, numerous bugfixes
|
2013-12-31 16:35:01 -06:00
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* The `float` type has been removed. Use `f32` or `f64` instead.
|
|
|
|
|
* A new facility for enabling experimental features (feature gating) has
|
|
|
|
|
been added, using the crate-level `#[feature(foo)]` attribute.
|
|
|
|
|
* Managed boxes (@) are now behind a feature gate
|
2014-07-04 23:22:59 -05:00
|
|
|
(`#[feature(managed_boxes)]`) in preparation for future removal. Use the
|
2013-12-31 16:35:01 -06:00
|
|
|
standard library's `Gc` or `Rc` types instead.
|
|
|
|
|
* `@mut` has been removed. Use `std::cell::{Cell, RefCell}` instead.
|
|
|
|
|
* Jumping back to the top of a loop is now done with `continue` instead of
|
|
|
|
|
`loop`.
|
|
|
|
|
* Strings can no longer be mutated through index assignment.
|
|
|
|
|
* Raw strings can be created via the basic `r"foo"` syntax or with matched
|
|
|
|
|
hash delimiters, as in `r###"foo"###`.
|
|
|
|
|
* `~fn` is now written `proc (args) -> retval { ... }` and may only be
|
|
|
|
|
called once.
|
|
|
|
|
* The `&fn` type is now written `|args| -> ret` to match the literal form.
|
|
|
|
|
* `@fn`s have been removed.
|
|
|
|
|
* `do` only works with procs in order to make it obvious what the cost
|
|
|
|
|
of `do` is.
|
2014-01-06 16:50:25 -06:00
|
|
|
* Single-element tuple-like structs can no longer be dereferenced to
|
|
|
|
|
obtain the inner value. A more comprehensive solution for overloading
|
|
|
|
|
the dereference operator will be provided in the future.
|
2013-12-31 16:35:01 -06:00
|
|
|
* The `#[link(...)]` attribute has been replaced with
|
|
|
|
|
`#[crate_id = "name#vers"]`.
|
|
|
|
|
* Empty `impl`s must be terminated with empty braces and may not be
|
|
|
|
|
terminated with a semicolon.
|
|
|
|
|
* Keywords are no longer allowed as lifetime names; the `self` lifetime
|
|
|
|
|
no longer has any special meaning.
|
|
|
|
|
* The old `fmt!` string formatting macro has been removed.
|
|
|
|
|
* `printf!` and `printfln!` (old-style formatting) removed in favor of
|
|
|
|
|
`print!` and `println!`.
|
|
|
|
|
* `mut` works in patterns now, as in `let (mut x, y) = (1, 2);`.
|
2014-01-06 16:50:25 -06:00
|
|
|
* The `extern mod foo (name = "bar")` syntax has been removed. Use
|
|
|
|
|
`extern mod foo = "bar"` instead.
|
2013-12-31 16:35:01 -06:00
|
|
|
* New reserved keywords: `alignof`, `offsetof`, `sizeof`.
|
|
|
|
|
* Macros can have attributes.
|
|
|
|
|
* Macros can expand to items with attributes.
|
|
|
|
|
* Macros can expand to multiple items.
|
|
|
|
|
* The `asm!` macro is feature-gated (`#[feature(asm)]`).
|
|
|
|
|
* Comments may be nested.
|
|
|
|
|
* Values automatically coerce to trait objects they implement, without
|
|
|
|
|
an explicit `as`.
|
|
|
|
|
* Enum discriminants are no longer an entire word but as small as needed to
|
|
|
|
|
contain all the variants. The `repr` attribute can be used to override
|
|
|
|
|
the discriminant size, as in `#[repr(int)]` for integer-sized, and
|
|
|
|
|
`#[repr(C)]` to match C enums.
|
|
|
|
|
* Non-string literals are not allowed in attributes (they never worked).
|
|
|
|
|
* The FFI now supports variadic functions.
|
|
|
|
|
* Octal numeric literals, as in `0o7777`.
|
|
|
|
|
* The `concat!` syntax extension performs compile-time string concatenation.
|
|
|
|
|
* The `#[fixed_stack_segment]` and `#[rust_stack]` attributes have been
|
|
|
|
|
removed as Rust no longer uses segmented stacks.
|
|
|
|
|
* Non-ascii identifiers are feature-gated (`#[feature(non_ascii_idents)]`).
|
|
|
|
|
* Ignoring all fields of an enum variant or tuple-struct is done with `..`,
|
|
|
|
|
not `*`; ignoring remaining fields of a struct is also done with `..`,
|
|
|
|
|
not `_`; ignoring a slice of a vector is done with `..`, not `.._`.
|
|
|
|
|
* `rustc` supports the "win64" calling convention via `extern "win64"`.
|
|
|
|
|
* `rustc` supports the "system" calling convention, which defaults to the
|
|
|
|
|
preferred convention for the target platform, "stdcall" on 32-bit Windows,
|
|
|
|
|
"C" elsewhere.
|
|
|
|
|
* The `type_overflow` lint (default: warn) checks literals for overflow.
|
|
|
|
|
* The `unsafe_block` lint (default: allow) checks for usage of `unsafe`.
|
|
|
|
|
* The `attribute_usage` lint (default: warn) warns about unknown
|
|
|
|
|
attributes.
|
|
|
|
|
* The `unknown_features` lint (default: warn) warns about unknown
|
|
|
|
|
feature gates.
|
|
|
|
|
* The `dead_code` lint (default: warn) checks for dead code.
|
|
|
|
|
* Rust libraries can be linked statically to one another
|
|
|
|
|
* `#[link_args]` is behind the `link_args` feature gate.
|
|
|
|
|
* Native libraries are now linked with `#[link(name = "foo")]`
|
|
|
|
|
* Native libraries can be statically linked to a rust crate
|
|
|
|
|
(`#[link(name = "foo", kind = "static")]`).
|
|
|
|
|
* Native OS X frameworks are now officially supported
|
|
|
|
|
(`#[link(name = "foo", kind = "framework")]`).
|
|
|
|
|
* The `#[thread_local]` attribute creates thread-local (not task-local)
|
|
|
|
|
variables. Currently behind the `thread_local` feature gate.
|
|
|
|
|
* The `return` keyword may be used in closures.
|
|
|
|
|
* Types that can be copied via a memcpy implement the `Pod` kind.
|
2014-01-06 16:50:25 -06:00
|
|
|
* The `cfg` attribute can now be used on struct fields and enum variants.
|
2013-12-31 16:35:01 -06:00
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* std: The `option` and `result` API's have been overhauled to make them
|
|
|
|
|
simpler, more consistent, and more composable.
|
|
|
|
|
* std: The entire `std::io` module has been replaced with one that is
|
|
|
|
|
more comprehensive and that properly interfaces with the underlying
|
|
|
|
|
scheduler. File, TCP, UDP, Unix sockets, pipes, and timers are all
|
|
|
|
|
implemented.
|
|
|
|
|
* std: `io::util` contains a number of useful implementations of
|
|
|
|
|
`Reader` and `Writer`, including `NullReader`, `NullWriter`,
|
|
|
|
|
`ZeroReader`, `TeeReader`.
|
|
|
|
|
* std: The reference counted pointer type `extra::rc` moved into std.
|
|
|
|
|
* std: The `Gc` type in the `gc` module will replace `@` (it is currently
|
|
|
|
|
just a wrapper around it).
|
2014-01-06 16:50:25 -06:00
|
|
|
* std: The `Either` type has been removed.
|
2013-12-31 16:35:01 -06:00
|
|
|
* std: `fmt::Default` can be implemented for any type to provide default
|
|
|
|
|
formatting to the `format!` macro, as in `format!("{}", myfoo)`.
|
|
|
|
|
* std: The `rand` API continues to be tweaked.

|
* std: The `rust_begin_unwind` function, useful for inserting breakpoints
|
2014-01-06 16:50:25 -06:00
|
|
|
on failure in gdb, is now named `rust_fail`.
|
|
|
|
|
* std: The `each_key` and `each_value` methods on `HashMap` have been
|
|
|
|
|
replaced by the `keys` and `values` iterators.
|
2013-12-31 16:35:01 -06:00
|
|
|
* std: Functions dealing with type size and alignment have moved from the
|
|
|
|
|
`sys` module to the `mem` module.
|
|
|
|
|
* std: The `path` module was written and API changed.
|
|
|
|
|
* std: `str::from_utf8` has been changed to cast instead of allocate.
|
|
|
|
|
* std: `starts_with` and `ends_with` methods added to vectors via the
|
|
|
|
|
`ImmutableEqVector` trait, which is in the prelude.
|
|
|
|
|
* std: Vectors can be indexed with the `get_opt` method, which returns `None`
|
|
|
|
|
if the index is out of bounds.
|
|
|
|
|
* std: Task failure no longer propagates between tasks, as the model was
|
|
|
|
|
complex, expensive, and incompatible with thread-based tasks.
|
|
|
|
|
* std: The `Any` type can be used for dynamic typing.
|
|
|
|
|
* std: `~Any` can be passed to the `fail!` macro and retrieved via
|
|
|
|
|
`task::try`.
|
|
|
|
|
* std: Methods that produce iterators generally do not have an `_iter`
|
|
|
|
|
suffix now.
|
|
|
|
|
* std: `cell::Cell` and `cell::RefCell` can be used to introduce mutability
|
|
|
|
|
roots (mutable fields, etc.). Use instead of e.g. `@mut`.
|
|
|
|
|
* std: `util::ignore` renamed to `prelude::drop`.
|
|
|
|
|
* std: Slices have `sort` and `sort_by` methods via the `MutableVector`
|
|
|
|
|
trait.
|
|
|
|
|
* std: `vec::raw` has seen a lot of cleanup and API changes.
|
|
|
|
|
* std: The standard library no longer includes any C++ code, and very
|
|
|
|
|
minimal C, eliminating the dependency on libstdc++.
|
|
|
|
|
* std: Runtime scheduling and I/O functionality has been factored out into
|
|
|
|
|
extensible interfaces and is now implemented by two different crates:
|
|
|
|
|
libnative, for native threading and I/O; and libgreen, for green threading
|
|
|
|
|
and I/O. This paves the way for using the standard library in more limited
|
2014-07-04 23:22:59 -05:00
|
|
|
embedded environments.
|
2013-12-31 16:35:01 -06:00
|
|
|
* std: The `comm` module has been rewritten to be much faster, have a
|
|
|
|
|
simpler, more consistent API, and to work for both native and green
|
|
|
|
|
threading.
|
|
|
|
|
* std: All libuv dependencies have been moved into the rustuv crate.
|
|
|
|
|
* native: New implementations of runtime scheduling on top of OS threads.
|
|
|
|
|
* native: New native implementations of TCP, UDP, file I/O, process spawning,
|
|
|
|
|
and other I/O.
|
|
|
|
|
* green: The green thread scheduler and message passing types are almost
|
|
|
|
|
entirely lock-free.
|
|
|
|
|
* extra: The `flatpipes` module had bitrotted and was removed.
|
|
|
|
|
* extra: All crypto functions have been removed and Rust now has a policy of
|
|
|
|
|
not reimplementing crypto in the standard library. In the future crypto
|
|
|
|
|
will be provided by external crates with bindings to established libraries.
|
|
|
|
|
* extra: `c_vec` has been modernized.
|
|
|
|
|
* extra: The `sort` module has been removed. Use the `sort` method on
|
|
|
|
|
mutable slices.
|

|
|
|
|
|
|
* Tooling
|
2013-12-31 16:35:01 -06:00
|
|
|
* The `rust` and `rusti` commands have been removed, due to lack of
|
|
|
|
|
maintenance.
|
|
|
|
|
* `rustdoc` was completely rewritten.
|
|
|
|
|
* `rustdoc` can test code examples in documentation.
|
|
|
|
|
* `rustpkg` can test packages with the argument, 'test'.
|
|
|
|
|
* `rustpkg` supports arbitrary dependencies, including C libraries.
|
|
|
|
|
* `rustc`'s support for generating debug info is improved again.
|
|
|
|
|
* `rustc` has better error reporting for unbalanced delimiters.
|
|
|
|
|
* `rustc`'s JIT support was removed due to bitrot.
|
|
|
|
|
* Executables and static libraries can be built with LTO (-Z lto)
|
|
|
|
|
* `rustc` adds a `--dep-info` flag for communicating dependencies to
|
|
|
|
|
build tools.

============================
|
2013-09-18 20:51:48 -05:00
|
|
|
|
2013-09-25 13:34:08 -05:00
|
|
|
* ~2200 changes, numerous bugfixes
|
2013-09-18 20:51:48 -05:00
|
|
|
|
|
|
|
|
* Language
|
|
|
|
|
* The `for` loop syntax has changed to work with the `Iterator` trait.
|
|
|
|
|
* At long last, unwinding works on Windows.
|
2013-09-19 18:50:49 -05:00
|
|
|
* Default methods are ready for use.
|
2013-09-18 20:51:48 -05:00
|
|
|
* Many trait inheritance bugs fixed.
|
|
|
|
|
* Owned and borrowed trait objects work more reliably.
|
|
|
|
|
* `copy` is no longer a keyword. It has been replaced by the `Clone` trait.
|
2013-09-17 23:02:11 -05:00
|
|
|
* rustc can omit emission of code for the `debug!` macro if it is passed
|
|
|
|
|
`--cfg ndebug`
|
2013-09-18 20:51:48 -05:00
|
|
|
* mod.rs is now "blessed". When loading `mod foo;`, rustc will now look
|
|
|
|
|
for foo.rs, then foo/mod.rs, and will generate an error when both are
|
|
|
|
|
present.
|
|
|
|
|
* Strings no longer contain trailing nulls. The new `std::c_str` module
|
|
|
|
|
provides new mechanisms for converting to C strings.
|
|
|
|
|
* The type of foreign functions is now `extern "C" fn` instead of `*u8'.
|
|
|
|
|
* The FFI has been overhauled such that foreign functions are called directly,
|
|
|
|
|
instead of through a stack-switching wrapper.
|
|
|
|
|
* Calling a foreign function must be done through a Rust function with the
|
|
|
|
|
`#[fixed_stack_segment]` attribute.
|
|
|
|
|
* The `externfn!` macro can be used to declare both a foreign function and
|
|
|
|
|
a `#[fixed_stack_segment]` wrapper at once.
|
|
|
|
|
* `pub` and `priv` modifiers on `extern` blocks are no longer parsed.
|
|
|
|
|
* `unsafe` is no longer allowed on extern fns - they are all unsafe.
|
|
|
|
|
* `priv` is disallowed everywhere except for struct fields and enum variants.
|
|
|
|
|
* `&T` (besides `&'static T`) is no longer allowed in `@T`.
|
|
|
|
|
* `ref` bindings in irrefutable patterns work correctly now.
|
|
|
|
|
* `char` is now prevented from containing invalid code points.
|
|
|
|
|
* Casting to `bool` is no longer allowed.
|
2013-09-23 16:17:58 -05:00
|
|
|
* `\0` is now accepted as an escape in chars and strings.
|
2013-09-18 20:51:48 -05:00
|
|
|
* `yield` is a reserved keyword.
|
|
|
|
|
* `typeof` is a reserved keyword.
|
|
|
|
|
* Crates may be imported by URL with `extern mod foo = "url";`.
|
|
|
|
|
* Explicit enum discriminants may be given as uints as in `enum E { V = 0u }`
|
|
|
|
|
* Static vectors can be initialized with repeating elements,
|
|
|
|
|
e.g. `static foo: [u8, .. 100]: [0, .. 100];`.
|
|
|
|
|
* Static structs can be initialized with functional record update,
|
|
|
|
|
e.g. `static foo: Foo = Foo { a: 5, .. bar };`.
|
|
|
|
|
* `cfg!` can be used to conditionally execute code based on the crate
|
|
|
|
|
configuration, similarly to `#[cfg(...)]`.
|
|
|
|
|
* The `unnecessary_qualification` lint detects unneeded module
|
|
|
|
|
prefixes (default: allow).
|
|
|
|
|
* Arithmetic operations have been implemented on the SIMD types in
|
|
|
|
|
`std::unstable::simd`.
|
|
|
|
|
* Exchange allocation headers were removed, reducing memory usage.
|
|
|
|
|
* `format!` implements a completely new, extensible, and higher-performance
|
|
|
|
|
string formatting system. It will replace `fmt!`.
|
|
|
|
|
* `print!` and `println!` write formatted strings (using the `format!`
|
|
|
|
|
extension) to stdout.
|
|
|
|
|
* `write!` and `writeln!` write formatted strings (using the `format!`
|
|
|
|
|
extension) to the new Writers in `std::rt::io`.
|
|
|
|
|
* The library section in which a function or static is placed may
|
|
|
|
|
be specified with `#[link_section = "..."]`.
|
|
|
|
|
* The `proto!` syntax extension for defining bounded message protocols
|
|
|
|
|
was removed.
|
2013-09-19 18:50:49 -05:00
|
|
|
* `macro_rules!` is hygienic for `let` declarations.
|
2013-09-18 20:51:48 -05:00
|
|
|
* The `#[export_name]` attribute specifies the name of a symbol.
|
|
|
|
|
* `unreachable!` can be used to indicate unreachable code, and fails
|
|
|
|
|
if executed.
|
|
|
|
|
|
|
|
|
|
* Libraries
|
|
|
|
|
* std: Transitioned to the new runtime, written in Rust.
|
|
|
|
|
* std: Added an experimental I/O library, `rt::io`, based on the new
|
|
|
|
|
runtime.
|
|
|
|
|
* std: A new generic `range` function was added to the prelude, replacing
|
|
|
|
|
`uint::range` and friends.
|
|
|
|
|
* std: `range_rev` no longer exists. Since range is an iterator it can be
|
|
|
|
|
reversed with `range(lo, hi).invert()`.
|
|
|
|
|
* std: The `chain` method on option renamed to `and_then`; `unwrap_or_default`
|
|
|
|
|
renamed to `unwrap_or`.
|
|
|
|
|
* std: The `iterator` module was renamed to `iter`.
|
|
|
|
|
* std: Integral types now support the `checked_add`, `checked_sub`, and
|
|
|
|
|
`checked_mul` operations for detecting overflow.
|
|
|
|
|
* std: Many methods in `str`, `vec`, `option, `result` were renamed for
|
|
|
|
|
consistency.
|
|
|
|
|
* std: Methods are standardizing on conventions for casting methods:
|
|
|
|
|
`to_foo` for copying, `into_foo` for moving, `as_foo` for temporary
|
|
|
|
|
and cheap casts.
|
|
|
|
|
* std: The `CString` type in `c_str` provides new ways to convert to and
|
|
|
|
|
from C strings.
|
|
|
|
|
* std: `DoubleEndedIterator` can yield elements in two directions.
|
|
|
|
|
* std: The `mut_split` method on vectors partitions an `&mut [T]` into
|
|
|
|
|
two splices.
|
|
|
|
|
* std: `str::from_bytes` renamed to `str::from_utf8`.
|
|
|
|
|
* std: `pop_opt` and `shift_opt` methods added to vectors.
|
|
|
|
|
* std: The task-local data interface no longer uses @, and keys are
|
|
|
|
|
no longer function pointers.
|
|
|
|
|
* std: The `swap_unwrap` method of `Option` renamed to `take_unwrap`.
|
|
|
|
|
* std: Added `SharedPort` to `comm`.
|
|
|
|
|
* std: `Eq` has a default method for `ne`; only `eq` is required
|
|
|
|
|
in implementations.
|
2013-09-19 18:50:49 -05:00
|
|
|
* std: `Ord` has default methods for `le`, `gt` and `ge`; only `lt`
|
2013-09-18 20:51:48 -05:00
|
|
|
is required in implementations.
|
|
|
|
|
* std: `is_utf8` performance is improved, impacting many string functions.
|
|
|
|
|
* std: `os::MemoryMap` provides cross-platform mmap.
|
|
|
|
|
* std: `ptr::offset` is now unsafe, but also more optimized. Offsets that
|
|
|
|
|
are not 'in-bounds' are considered undefined.
|
|
|
|
|
* std: Many freestanding functions in `vec` removed in favor of methods.
|
|
|
|
|
* std: Many freestanding functions on scalar types removed in favor of
|
|
|
|
|
methods.
|
|
|
|
|
* std: Many options to task builders were removed since they don't make
|
|
|
|
|
sense in the new scheduler design.
|
|
|
|
|
* std: More containers implement `FromIterator` so can be created by the
|
|
|
|
|
`collect` method.
|
|
|
|
|
* std: More complete atomic types in `unstable::atomics`.
|
|
|
|
|
* std: `comm::PortSet` removed.
|
|
|
|
|
* std: Mutating methods in the `Set` and `Map` traits have been moved into
|
|
|
|
|
the `MutableSet` and `MutableMap` traits. `Container::is_empty`,
|
|
|
|
|
`Map::contains_key`, `MutableMap::insert`, and `MutableMap::remove` have
|
|
|
|
|
default implementations.
|
2013-09-23 16:17:58 -05:00
|
|
|
* std: Various `from_str` functions were removed in favor of a generic
|
|
|
|
|
`from_str` which is available in the prelude.
|
|
|
|
|
* std: `util::unreachable` removed in favor of the `unreachable!` macro.
|
2013-09-18 20:51:48 -05:00
|
|
|
* extra: `dlist`, the doubly-linked list was modernized.
|
|
|
|
|
* extra: Added a `hex` module with `ToHex` and `FromHex` traits.
|
|
|
|
|
* extra: Added `glob` module, replacing `std::os::glob`.
|
|
|
|
|
* extra: `rope` was removed.
|
|
|
|
|
* extra: `deque` was renamed to `ringbuf`. `RingBuf` implements `Deque`.
|
|
|
|
|
* extra: `net`, and `timer` were removed. The experimental replacements
|
|
|
|
|
are `std::rt::io::net` and `std::rt::io::timer`.
|
|
|
|
|
* extra: Iterators implemented for `SmallIntMap`.
|
|
|
|
|
* extra: Iterators implemented for `Bitv` and `BitvSet`.
|
|
|
|
|
* extra: `SmallIntSet` removed. Use `BitvSet`.
|
|
|
|
|
* extra: Performance of JSON parsing greatly improved.
|
|
|
|
|
* extra: `semver` updated to SemVer 2.0.0.
|
|
|
|
|
* extra: `term` handles more terminals correctly.
|
|
|
|
|
* extra: `dbg` module removed.
|
2013-09-23 16:17:58 -05:00
|
|
|
* extra: `par` module removed.
|
|
|
|
|
* extra: `future` was cleaned up, with some method renames.
|
|
|
|
|
* extra: Most free functions in `getopts` were converted to methods.
|
2013-09-18 20:51:48 -05:00
|
|
|
|
|
|
|
|
* Other
|
|
|
|
|
* rustc's debug info generation (`-Z debug-info`) is greatly improved.
|
|
|
|
|
* rustc accepts `--target-cpu` to compile to a specific CPU architecture,
|
|
|
|
|
similarly to gcc's `--march` flag.
|
2013-09-20 13:49:27 -05:00
|
|
|
* rustc's performance compiling small crates is much better.
|
2013-09-18 20:51:48 -05:00
|
|
|
* rustpkg has received many improvements.
|
|
|
|
|
* rustpkg supports git tags as package IDs.
|
|
|
|
|
* rustpkg builds into target-specific directories so it can be used for
|
|
|
|
|
cross-compiling.
|
|
|
|
|
* The number of concurrent test tasks is controlled by the environment
|
|
|
|
|
variable RUST_TEST_TASKS.
|
|
|
|
|
* The test harness can now report metrics for benchmarks.
|
|
|
|
|
* All tools have man pages.
|
|
|
|
|
* Programs compiled with `--test` now support the `-h` and `--help` flags.
|
|
|
|
|
* The runtime uses jemalloc for allocations.
|
|
|
|
|
* Segmented stacks are temporarily disabled as part of the transition to
|
|
|
|
|
the new runtime. Stack overflows are possible!
|
2013-09-22 01:25:48 -05:00
|
|
|
* A new documentation backend, rustdoc_ng, is available for use. It is
|
|
|
|
|
still invoked through the normal `rustdoc` command.

|
|
* Language
|
2013-06-25 01:46:38 -05:00
|
|
|
* `impl`s no longer accept a visibility qualifier. Put them on methods
|
|
|
|
|
instead.
|
2013-06-15 18:57:37 -05:00
|
|
|
* The borrow checker has been rewritten with flow-sensitivity, fixing
|
|
|
|
|
many bugs and inconveniences.
|
2013-06-13 01:16:22 -05:00
|
|
|
* The `self` parameter no longer implicitly means `&'self self`,
|
|
|
|
|
and can be explicitly marked with a lifetime.
|
2013-06-30 17:02:52 -05:00
|
|
|
* Overloadable compound operators (`+=`, etc.) have been temporarily
|
|
|
|
|
removed due to bugs.
|
2013-06-15 18:57:37 -05:00
|
|
|
* The `for` loop protocol now requires `for`-iterators to return `bool`
|
|
|
|
|
so they compose better.
|
2013-06-30 17:02:52 -05:00
|
|
|
* The `Durable` trait is replaced with the `'static` bounds.
|
2013-06-25 01:46:38 -05:00
|
|
|
* Trait default methods work more often.
|
2013-06-30 17:02:52 -05:00
|
|
|

|
|
* ~2100 changes, numerous bugfixes
|
2013-03-11 20:27:41 -05:00
|
|
|
|
|
|
|
|
* Syntax changes
|
|
|
|
|
* The self type parameter in traits is now spelled `Self`
|
2013-03-22 13:59:59 -05:00
|
|
|
* The `self` parameter in trait and impl methods must now be explicitly
|
|
|
|
|
named (for example: `fn f(&self) { }`). Implicit self is deprecated.
|
2013-03-26 14:28:04 -05:00
|
|
|
* Static methods no longer require the `static` keyword and instead
|
|
|
|
|
are distinguished by the lack of a `self` parameter
|
2013-03-11 20:27:41 -05:00
|
|
|
* Replaced the `Durable` trait with the `'static` lifetime
|
|
|
|
|
* The old closure type syntax with the trailing sigil has been
|
|
|
|
|
removed in favor of the more consistent leading sigil
|
|
|
|
|
* `super` is a keyword, and may be prefixed to paths
|
|
|
|
|
* Trait bounds are separated with `+` instead of whitespace
|
|
|
|
|
* Traits are implemented with `impl Trait for Type`
|
|
|
|
|
instead of `impl Type: Trait`
|
2013-03-26 14:28:04 -05:00
|
|
|
* Lifetime syntax is now `&'l foo` instead of `&l/foo`
|
2013-03-11 20:27:41 -05:00
|
|
|
* The `export` keyword has finally been removed
|
2013-03-22 13:59:59 -05:00
|
|
|
* The `move` keyword has been removed (see "Semantic changes")
|
2013-03-11 20:27:41 -05:00
|
|
|
* The interior mutability qualifier on vectors, `[mut T]`, has been
|
|
|
|
|
removed. Use `&mut [T]`, etc.
|
|
|
|
|
* `mut` is no longer valid in `~mut T`. Use inherited mutability
|
|
|
|
|
* `fail` is no longer a keyword. Use `fail!()`
|
|
|
|
|
* `assert` is no longer a keyword. Use `assert!()`
|
|
|
|
|
* `log` is no longer a keyword. use `debug!`, etc.
|
|
|
|
|
* 1-tuples may be represented as `(T,)`
|
|
|
|
|

|
|
|
|
|
`@mut T`, `core::mut` or `core::cell`
|
|
|
|
|
* `extern mod { ... }` is no longer valid syntax for foreign
|
|
|
|
|
function modules. Use extern blocks: `extern { ... }`
|
2013-03-31 16:37:04 -05:00

|
|
* Pattern matching over vectors improved and expanded
|
2013-03-22 14:41:42 -05:00
|
|
|
* `const` renamed to `static` to correspond to lifetime name,
|
|
|
|
|
and make room for future `static mut` unsafe mutable globals.
|
2013-03-26 14:28:04 -05:00
|
|
|
* Replaced `#[deriving_eq]` with `#[deriving(Eq)]`, etc.

|
|
`#[deriving(Clone)]`
|
2013-03-26 14:28:04 -05:00
|
|
|

|
|
|
instead of `foo as Bar`.

2013-03-31 16:37:04 -05:00
|
|
|
* Fixed length vector types are now written as `[int, .. 3]`
|
|
|
|
|
instead of `[int * 3]`.
|
|
|
|
|
* Fixed length vector types can express the length as a constant
|
|
|
|
|
expression. (ex: `[int, .. GL_BUFFER_SIZE - 2]`)
|
2013-03-11 20:27:41 -05:00

|
|
|
|
|
* Semantic changes
|
2013-03-13 15:47:49 -05:00
|
|
|
* Types with owned pointers or custom destructors move by default,
|
|
|
|
|
eliminating the `move` keyword
|

|
|
|
|
|
* The name of the main function can be customized using #[main]
|
|
|
|
|
* The default type of an inferred closure is &fn instead of @fn
|
2013-03-26 14:28:04 -05:00
|
|
|
* `use` statements may no longer be "chained" - they cannot import
|
|
|
|
|
identifiers imported by previous `use` statements
|
|
|
|
|
* `use` statements are crate relative, importing from the "top"
|
|
|
|
|
of the crate by default. Paths may be prefixed with `super::`
|
|
|
|
|
or `self::` to change the search behavior.
|
2013-03-11 20:27:41 -05:00
|
|
|

|
|
* Macros leave scope at the end of modules, unless that module is
|
|
|
|
|
tagged with #[macro_escape]
