1. Produced more unique types than is necessary. This increases memory consumption.
2. Linking the type parameter to its definition *seems* like a good idea, but it
encourages reliance on the bounds listing.
3. It made pretty-printing harder and in particular was causing bad error messages
when errors occurred before the `TypeParameterDef` entries were fully stored.
This distributes docs in a separate package called rust-docs. The rust-packaging
project will combine it with Rust and Cargo into a single installer in a variety of formats.
The first six commits are from an earlier PR (#19858) and have already been reviewed. This PR makes an awful hack in the compiler to accommodate slices both natively and in the index a range form. After a snapshot we can hopefully add the new Index impls and then we can remove these awful hacks.
r? @nikomatsakis (or anyone who knows the compiler, really)
This patch for #15877 uses Antlr's input lookahead (`_input.LA(1) != '.'`) to solve the conflict between the LIT_FLOAT and the range syntax.
Note that in order to execute the grammar tests, #20245 should land first.
This commit performs a second pass over the `std::string` module, performing the
following actions:
* The name `std::string` is now stable.
* The `String::from_utf8` function is now stable after having been altered to
return a new `FromUtf8Error` structure. The `FromUtf8Error` structure is now
stable as well as its `into_bytes` and `utf8_error` methods.
* The `String::from_utf8_lossy` function is now stable.
* The `String::from_chars` method is now deprecated in favor of `.collect()`
* The `String::from_raw_parts` method is now stable
* The `String::from_str` function remains experimental
* The `String::from_raw_buf` function remains experimental
* The `String::from_raw_buf_len` function remains experimental
* The `String::from_utf8_unchecked` function is now stable
* The `String::from_char` function is now deprecated in favor of
`repeat(c).take(n).collect()`
* The `String::grow` function is now deprecated in favor of
`.extend(repeat(c).take(n)`
* The `String::capacity` method is now stable
* The `String::reserve` method is now stable
* The `String::reserve_exact` method is now stable
* The `String::shrink_to_fit` method is now stable
* The `String::pop` method is now stable
* The `String::as_mut_vec` method is now stable
* The `String::is_empty` method is now stable
* The `IntoString` trait is now deprecated (there are no implementors)
* The `String::truncate` method is now stable
* The `String::insert` method is now stable
* The `String::remove` method is now stable
* The `String::push` method is now stable
* The `String::push_str` method is now stable
* The `String::from_utf16` function is now stable after its error type has now
become an opaque structure to carry more semantic information in the future.
A number of these changes are breaking changes, but the migrations should be
fairly straightforward on a case-by-case basis (outlined above where possible).
[breaking-change]
This library is now published on crates.io as the `term` crate, so the in-tree
version is now deprecated. Once stability warnings are enabled, this library
will automatically be gated.
According to http://llvm.org/docs/LangRef.html#data-layout correct syntax
for data layout is `a:<abi>:<pref>` so it looks like `a0:<abi>:<pref>` is
either a typo or outdated syntax (as it goes back pretty deep in time)
The methods `from_bits` and `from_bits_truncate` were missing from the
list of generated methods. Didn't see a useful way to abbreviate, so
added with the same docstrings used in the macro definition.
Since runtime is removed, rust has no tasks anymore and everything is moving
from being task-* to thread-*. Let’s rename TaskRng as well!
This is a breaking change. If a breaking change for consistency is not desired, feel free to close.
Fixes#19707.
In terms of output, it currently uses the form `argument #1`, `argument #2`, etc. If anyone has any better suggestions I would be glad to consider them.
