This commit makes several changes to the stability index infrastructure: * Stability levels are now inherited lexically, i.e., each item's stability level becomes the default for any nested items. * The computed stability level for an item is stored as part of the metadata. When using an item from an external crate, this data is looked up and cached. * The stability lint works from the computed stability level, rather than manual stability attribute annotations. However, the lint still checks only a limited set of item uses (e.g., it does not check every component of a path on import). This will be addressed in a later PR, as part of issue #8962. * The stability lint only applies to items originating from external crates, since the stability index is intended as a promise to downstream crates. * The "experimental" lint is now _allow_ by default. This is because almost all existing crates have been marked "experimental", pending library stabilization. With inheritance in place, this would generate a massive explosion of warnings for every Rust program. The lint should be changed back to deny-by-default after library stabilization is complete. * The "deprecated" lint still warns by default. The net result: we can begin tracking stability index for the standard libraries as we stabilize, without impacting most clients. Closes #13540. |

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Quick Start
- Download a binary installer for your platform.
- Read the tutorial.
- Enjoy!
Note: Windows users can read the detailed getting started notes on the wiki.
Building from Source
-
Make sure you have installed the dependencies:
g++4.7 orclang++3.xpython2.6 or later (but not 3.x)perl5.0 or later- GNU
make3.81 or later curlgit
-
Download and build Rust:
You can either download a tarball or build directly from the repo.
To build from the tarball do:
$ curl -O http://static.rust-lang.org/dist/rust-nightly.tar.gz $ tar -xzf rust-nightly.tar.gz $ cd rust-nightlyOr to build from the repo do:
$ git clone https://github.com/rust-lang/rust.git $ cd rustNow that you have Rust's source code, you can configure and build it:
$ ./configure $ make && make installNote: You may need to use
sudo make installif you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a--prefixargument toconfigure. Various other options are also supported, pass--helpfor more information on them.When complete,
make installwill place several programs into/usr/local/bin:rustc, the Rust compiler, andrustdoc, the API-documentation tool. system. -

Enjoy!
Notes
Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.
Snapshot binaries are currently built and tested on several platforms:
- Windows (7, 8, Server 2008 R2), x86 only
- Linux (2.6.18 or later, various distributions), x86 and x86-64
- OSX 10.7 (Lion) or greater, x86 and x86-64
You may find that other platforms work, but these are our officially supported build environments that are most likely to work.
Rust currently needs about 1.5 GiB of RAM to build without swapping; if it hits swap, it will take a very long time to build.
There is a lot more documentation in the wiki.
