Alex Crichton 1fbca8824a std: Fully stabilize Option<T>
This commit takes a second pass through the `std::option` module to fully
stabilize any lingering methods inside of it.

These items were made stable as-is

* Some
* None
* as_mut
* expect
* unwrap
* unwrap_or
* unwrap_or_else
* map
* map_or
* map_or_else
* and_then
* or_else
* unwrap_or_default
* Default implementation
* FromIterator implementation
* Copy implementation

These items were made stable with modifications

* iter - now returns a struct called Iter
* iter_mut - now returns a struct called IterMut
* into_iter - now returns a struct called IntoIter, Clone is never implemented

This is a breaking change due to the modifications to the names of the iterator
types returned. Code referencing the old names should updated to referencing the
newer names instead. This is also a breaking change due to the fact that
`IntoIter` no longer implements the `Clone` trait.

These items were explicitly not stabilized

* as_slice - waiting on indexing conventions
* as_mut_slice - waiting on conventions with as_slice as well
* cloned - the API was still just recently added
* ok_or - API remains experimental
* ok_or_else - API remains experimental

The Rust Programming Language

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

Quick Start

  1. Download a binary installer for your platform.
  2. Read the guide.
  3. Enjoy!

Note: Windows users can read the detailed using Rust on Windows notes on the wiki.

Building from Source

  1. Make sure you have installed the dependencies:

    • g++ 4.7 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
    • git
  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 https://static.rust-lang.org/dist/rust-nightly.tar.gz
     $ tar -xzf rust-nightly.tar.gz
     $ cd rust-nightly
    

    Or to build from the repo do:

     $ git clone https://github.com/rust-lang/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.

  3. Read the guide.

  4. Enjoy!

Building on Windows

To easily build on windows we can use MSYS2:

  1. Grab the latest MSYS2 installer and go through the installer.

  2. Now from the MSYS2 terminal we want to install the mingw64 toolchain and the other tools we need.

     $ pacman -S mingw-w64-i686-toolchain
     $ pacman -S base-devel
    
  3. With that now start mingw32_shell.bat from where you installed MSYS2 (i.e. C:\msys).

  4. From there just navigate to where you have Rust's source code, configure and build it:

     $ ./configure
     $ make && make install
    

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 and x86-64 (64-bit support added in Rust 0.12.0)
  • 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.
