The compiler was updated to recognize that implementations for ty_uniq(..) are allowed if the Box lang item is located in the current crate. This enforces the idea that libcore cannot allocated, and moves all related trait implementations from libcore to libstd. This is a breaking change in that the AnyOwnExt trait has moved from the any module to the owned module. Any previous users of std::any::AnyOwnExt should now use std::owned::AnyOwnExt instead. This was done because the trait is intended for Box traits and only Box traits. [breaking-change]

|
//! # The Rust Standard Library
|
|
//!
|
|
//! The Rust Standard Library provides the essential runtime
|
|
//! functionality for building portable Rust software.
|
|
//! It is linked to all Rust crates by default.
|
|
//!
|
|
//! ## Intrinsic types and operations
|
|
//!
|
|
//! The [`ptr`](../core/ptr/index.html), [`mem`](../core/mem/index.html),
|
|
//! and [`cast`](../core/cast/index.html) modules deal with unsafe pointers,
|
|
//! memory manipulation, and coercion.
|
|
//! [`kinds`](../core/kinds/index.html) defines the special built-in traits,
|
|
//! and [`raw`](../core/raw/index.html) the runtime representation of Rust types.
|
|
//! These are some of the lowest-level building blocks of Rust
|
|
//! abstractions.
|
|
//!
|
|
//! ## Math on primitive types and math traits
|
|
//!
|
|
//! Although basic operations on primitive types are implemented
|
|
//! directly by the compiler, the standard library additionally
|
|
//! defines many common operations through traits defined in
|
|
//! mod [`num`](num/index.html).
|
|
//!
|
|
//! ## Pervasive types
|
|
//!
|
|
//! The [`option`](option/index.html) and [`result`](result/index.html)
|
|
//! modules define optional and error-handling types, `Option` and `Result`.
|
|
//! [`iter`](../core/iter/index.html) defines Rust's iterator protocol
|
|
//! along with a wide variety of iterators.
|
|
//! [`Cell` and `RefCell`](../core/cell/index.html) are for creating types that
|
|
//! manage their own mutability.
|
|
//!
|
|
//! ## Vectors, slices and strings
|
|
//!
|
|
//! The common container type, `Vec`, a growable vector backed by an
|
|
//! array, lives in the [`vec`](vec/index.html) module. References to
|
|
//! arrays, `&[T]`, more commonly called "slices", are built-in types
|
|
//! for which the [`slice`](slice/index.html) module defines many
|
|
//! methods.
|
|
//!
|
|
//! UTF-8 strings, `~str` and `&str`, are built-in types, and the
|
|
//! standard library defines methods for them on a variety of traits
|
|
//! in the [`str`](str/index.html) module. Rust strings are immutable;
|
|
//! use the `StrBuf` type defined in [`strbuf`](strbuf/index.html)
|
|
//! for a mutable string builder.
|
|
//!
|
|
//! For converting to strings use the [`format!`](fmt/index.html)
|
|
//! macro, and for converting from strings use the
|
|
//! [`FromStr`](from_str/index.html) trait.
|
|
//!
|
|
//! ## Platform abstractions
|
|
//!
|
|
//! Besides basic data types, the standard library is largely concerned
|
|
//! with abstracting over differences in common platforms, most notably
|
|
//! Windows and Unix derivatives. The [`os`](os/index.html) module
|
|
//! provides a number of basic functions for interacting with the
|
|
//! operating environment, including program arguments, environment
|
|
//! variables, and directory navigation. The [`path`](path/index.html)
|
|
//! module encapsulates the platform-specific rules for dealing
|
|
//! with file paths.
|
|
//!
|
|
//! `std` also includes modules for interoperating with the
|
|
//! C language: [`c_str`](c_str/index.html) and
|
|
//! [`c_vec`](c_vec/index.html).
|
|
//!
|
|
//! ## Concurrency, I/O, and the runtime
|
|
//!
|
|
//! The [`task`](task/index.html) module contains Rust's threading abstractions,
|
|
//! while [`comm`](comm/index.html) contains the channel types for message
|
|
//! passing. [`sync`](sync/index.html) contains further, primitive, shared
|
|
//! memory types, including [`atomics`](sync/atomics/index.html).
|
|
//!
|
|
//! Common types of I/O, including files, TCP, UPD, pipes, Unix domain sockets,
|
|
//! timers, and process spawning, are defined in the [`io`](io/index.html) module.
|
|
//!
|
|
//! Rust's I/O and concurrency depends on a small runtime interface
|
|
//! that lives, along with its support code, in mod [`rt`](rt/index.html).
|
|
//! While a notable part of the standard library's architecture, this
|
|
//! module is not intended for public use.
|
|
//!
|
|
//! ## The Rust prelude and macros
|
|
//!
|
|
//! Finally, the [`prelude`](prelude/index.html) defines a
|
|
//! common set of traits, types, and functions that are made available
|
|
//! to all code by default. [`macros`](macros/index.html) contains
|
|
//! all the standard macros, such as `assert!`, `fail!`, `println!`,
|
|
//! and `format!`, also available to all Rust code.
