Huon Wilson a39056e614 std: convert first_non_utf8_byte to use the iterator. 
This makes it very slightly faster, especially when the string is valid
UTF-8, and completely removes the use of `unsafe` from the first half.

Before:

    from_utf8_lossy_100_ascii              ... bench:       151 ns/iter (+/- 17)
    from_utf8_lossy_100_invalid            ... bench:       447 ns/iter (+/- 33)
    from_utf8_lossy_100_multibyte          ... bench:       135 ns/iter (+/- 4)
    from_utf8_lossy_invalid                ... bench:       124 ns/iter (+/- 10

After:

    from_utf8_lossy_100_ascii              ... bench:       119 ns/iter (+/- 8)
    from_utf8_lossy_100_invalid            ... bench:       454 ns/iter (+/- 16)
    from_utf8_lossy_100_multibyte          ... bench:       116 ns/iter (+/- 9)
    from_utf8_lossy_invalid                ... bench:       119 ns/iter (+/- 9)

The Rust Programming Language

This is a compiler for Rust, including standard libraries, tools and documentation.

Quick Start

Windows

  1. Download and use the installer and MinGW.
  2. Read the tutorial.
  3. Enjoy!

Note: Windows users can read the detailed getting started notes on the wiki.

Linux / OS X

  1. Make sure you have installed the dependencies:

    • g++ 4.4 or clang++ 3.x
    • python 2.6 or later (but not 3.x)
    • perl 5.0 or later
    • GNU make 3.81 or later
    • curl

  2. 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-0.9

    Or to build from the repo do:

     $ git clone https://github.com/mozilla/rust.git
 $ cd rust

    Now that you have Rust's source code, you can configure and build it:

     $ ./configure
 $ make && make install

    Note: You may need to use sudo make install if you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a --prefix argument to configure. Various other options are also supported, pass --help for more information on them.

    When complete, make install will place several programs into /usr/local/bin: rustc, the Rust compiler, and rustdoc, the API-documentation tool. system.

  3. Read the tutorial.

  4. 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.
