A few notable improvements were implemented to cut down on the number of aborts triggered by the standard library when a local task is not found. * Primarily, the unwinding functionality was restructured to support an unsafe top-level function, `try`. This function invokes a closure, capturing any failure which occurs inside of it. The purpose of this function is to be as lightweight of a "try block" as possible for rust, intended for use when the runtime is difficult to set up. This function is *not* meant to be used by normal rust code, nor should it be consider for use with normal rust code. * When invoking spawn(), a `fail!()` is triggered rather than an abort. * When invoking LocalIo::borrow(), which is transitively called by all I/O constructors, None is returned rather than aborting to indicate that there is no local I/O implementation. A test case was also added showing the variety of things that you can do without a runtime or task set up now. In general, this is just a refactoring to abort less quickly in the standard library when a local task is not found. |

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/mozilla/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. -
Read the tutorial.

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.
