The printing of the error message on stack overflow had two sometimes false assumptions previously. The first is that a local task was always available (it called Local::take) and the second is that it used `println!` instead of manually writing. The first assumption isn't necessarily true because while stack overflow will likely only be detected in situations that a local task is available, it's not guaranteed to always be in TLS. For example, during a `println!` call a task may be blocking, causing it to be unavailable. By using Local::try_take(), we can be resilient against these occurrences. The second assumption could lead to odd behavior because the stdout logger can be overwritten to run arbitrary code. Currently this should be possible, but the utility is much diminished because a stack overflow translates to an abort() instead of a failure. |

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Quick Start
Windows
- Download and use the installer and MinGW.
- Read the tutorial.
- Enjoy!
Note: Windows users can read the detailed getting started notes on the wiki.
Linux / OS X
-
Make sure you have installed the dependencies:
g++4.4 orclang++3.xpython2.6 or later (but not 3.x)perl5.0 or later- GNU
make3.81 or later curl
-
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-0.9.tar.gz $ tar -xzf rust-0.9.tar.gz $ cd rust-0.9Or 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.
