Kevin Ballard bf1e065371 Remove FromIterator impl for ~[T]
As part of the shift from ~[T] to Vec<T>, recently ~[T] was made
non-growable. However, the FromIterator implementation for ~[T] was left
intact (albeit implemented inefficiently), which basically provided a
loophole to grow a ~[T] despite its non-growable nature. This is a
problem, both for performance reasons and because it encourages APIs to
continue returning ~[T] when they should return Vec<T>. Removing
FromIterator forces these APIs to adopt the correct type.

Furthermore, during today's weekly meeting it was decided that we should
remove all instances of ~[T] from the standard libraries in favor of
Vec<T>. Removing the FromIterator impl makes sense to do as a result.

This commit only includes the removal of the FromIterator impl. The
subsequent commits involve handling all of the breakage that results,
including changing APIs to use Vec<T> instead of ~[T]. The precise API
changes are documented in the subsequent commit messages, but each
commit is not individually marked as a breaking change.

Finally, a new trait FromVec is introduced that provides a mechanism to
convert Vec<T> back into ~[T] if truly necessary. It is a bit awkward to
use by design, and is anticipated that it will be more useful in a
post-DST world to convert to an arbitrary Foo<[T]> smart pointer.

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 tutorial.
  3. Enjoy!

Note: Windows users can read the detailed getting started 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 http://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/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.
