bors 679102109f auto merge of #8554 : michaelwoerister/rust/generics, r=brson This pull request includes support for generic functions and self arguments in methods, and combinations thereof. This also encompasses any kind of trait methods, regular and static, with and without default implementation. The implementation is backed up by a felt ton of test cases `:)` This is a very important step towards being able to compile larger programs with debug info, since practically any generic function caused an ICE before. One point worth discussing is that activating debug info now automatically (and silently) sets the `no_monomorphic_collapse` flag. Otherwise debug info would show wrong type names in all but one instance of the monomorphized function. Another thing to note is that the handling of generic types does not strictly follow the DWARF specification. That is, variables with type `T` (where `T=int`) are described as having type `int` and not as having type `T`. In other words, we are losing information whether a variable has been declared with a type parameter as its type. In practice this should not make much of difference though since the concrete type is mostly what one is interested in. I'll post an issue later so this won't be forgotten. Also included are a number of bug fixes: * Closes #1758 * Closes #8513 * Closes #8443 * Fixes handling of field names in tuple structs * Fixes and re-enables test case for option-like enums that relied on undefined behavior before * Closes #1339 (should have been closed a while ago) Cheers, Michael		2013-08-17 15:22:04 -07:00

The Rust Programming Language

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

Quick Start

Windows

Download and use the installer.
Read the tutorial.
Enjoy!

Note: Windows users should read the detailed getting started notes on the wiki. Even when using the binary installer the Windows build requires a MinGW installation, the precise details of which are not discussed here.

Linux / OS X

Install the prerequisites (if not already installed)
- 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
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-0.7.tar.gz
 $ tar -xzf rust-0.7.tar.gz
 $ cd rust-0.7
```
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
```
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; rustdoc, the API-documentation tool, and rustpkg, the Rust package manager and build system.
Read the tutorial.
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, Server 2008 R2), x86 only
Linux (various distributions), x86 and x86-64
OSX 10.6 ("Snow Leopard") or greater, x86 and x86-64

You may find that other platforms work, but these are our "tier 1" supported build environments that are most likely to work.

Rust currently needs about 1.8G of RAM to build without swapping; if it hits swap, it will take a very long time to build.

There is lots more documentation in the wiki.
