bors 8c00357f9d auto merge of #15999 : Kimundi/rust/fix_folder, r=nikomatsakis Note: This PR is motivated by an attempt to write an custom syntax extension that tried to use `syntax::fold`, and that could only do so by fixing bugs in it and copying out private functions. --- Refactored `syntax::fold` Prior to this, the code there had a few issues: - Default implementations inconsistenly either had the prefix `noop_` or not. - Some default methods where implemented in terms of a public noop function for user code to call, others where implemented directly on the trait and did not allow users of the trait to reuse the code. - Some of the default implementations where private, and thus not reusable for other implementors. - There where some bugs where default implemntations called other default implementations directly, rather than to the underlying Folder, with the result of some ast nodes never being visted even if the user implemented that method. (For example, the current Folder never folded struct fields) This commit solves this situation somewhat radically by making __all__ `fold_...` functions in the module into Folder methods, and implementing them all in terms of public `noop_...` functions for other implementors to call out to. Some public functions had to be renamed to fit the new system, so this is a breaking change. --- Also added a few trait implementations to `ast` types		2014-07-31 16:41:36 +00:00

The Rust Programming Language

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

Quick Start

Download a binary installer for your platform.
Read the tutorial.
Enjoy!

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

Building from Source

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
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/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.
Read the tutorial.
Enjoy!

Building on Windows

To easily build on windows we can use MSYS2:

Grab the latest MSYS2 installer and go through the installer.
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
```
With that now start mingw32_shell.bat from where you installed MSYS2 (i.e. C:\msys).
From there just navigate to where you have Rust's source code, configure and build it:
```
 $ ./configure --build=i686-pc-mingw32
 $ 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 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.
