bors b3afb16d24 Auto merge of #28491 - dotdash:noadjust, r=nikomatsakis 
That allows us to keep using trans_into() in case of adjustments that
may actually be ignored in trans because they are a plain deref/ref pair
with no overloaded deref or unsizing.

The Rust Programming Language

Rust is a fast systems programming language that guarantees memory safety and offers painless concurrency (no data races). It does not employ a garbage collector and has minimal runtime overhead.

This repo contains the code for the compiler (rustc), as well as standard libraries, tools and documentation for Rust.

Quick Start

Read "Installing Rust" from The Book.

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)
    • GNU make 3.81 or later
    • curl
    • git

  2. Clone the source with git:

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

  1. Build and install:

    $ ./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. This install does not include Cargo, Rust's package manager, which you may also want to build.

Building on Windows

MSYS2 can be used to easily build Rust on Windows:

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

  2. From the MSYS2 terminal, install the mingw64 toolchain and other required tools.

    # Update package mirrors (may be needed if you have a fresh install of MSYS2)
$ pacman -Sy pacman-mirrors

# Choose one based on platform:
$ pacman -S mingw-w64-i686-toolchain
$ pacman -S mingw-w64-x86_64-toolchain

$ pacman -S base-devel

  3. Run mingw32_shell.bat or mingw64_shell.bat from wherever you installed MSYS2 (i.e. C:\msys), depending on whether you want 32-bit or 64-bit Rust.

  4. Navigate to Rust's source code, configure and build it:

    $ ./configure
$ make && make install

Building Documentation

If you’d like to build the documentation, it’s almost the same:

./configure
$ make docs

Building the documentation requires building the compiler, so the above details will apply. Once you have the compiler built, you can

$ make docs NO_REBUILD=1

To make sure you don’t re-build the compiler because you made a change to some documentation.

The generated documentation will appear in a top-level doc directory, created by the make rule.

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:

Platform \ Architecture x86 x86_64
Windows (7, 8, Server 2008 R2) ✓ ✓
Linux (2.6.18 or later) ✓ ✓
OSX (10.7 Lion or later) ✓ ✓

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 more advice about hacking on Rust in CONTRIBUTING.md.

Getting Help

The Rust community congregates in a few places:

Contributing

To contribute to Rust, please see CONTRIBUTING.

Rust has an IRC culture and most real-time collaboration happens in a variety of channels on Mozilla's IRC network, irc.mozilla.org. The most popular channel is #rust, a venue for general discussion about Rust, and a good place to ask for help.
