bors 81c022317a auto merge of #14427 : alexcrichton/rust/librand, r=huonw This commit shuffles around some of the `rand` code, along with some reorganization. The new state of the world is as follows: * The librand crate now only depends on libcore. This interface is experimental. * The standard library has a new module, `std::rand`. This interface will eventually become stable. Unfortunately, this entailed more of a breaking change than just shuffling some names around. The following breaking changes were made to the rand library: * Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which will return an infinite stream of random values. Previous behavior can be regained with `rng.gen_iter().take(n).collect()` * Rng::gen_ascii_str() was removed. This has been replaced with Rng::gen_ascii_chars() which will return an infinite stream of random ascii characters. Similarly to gen_iter(), previous behavior can be emulated with `rng.gen_ascii_chars().take(n).collect()` * {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all relied on being able to use an OSRng for seeding, but this is no longer available in librand (where these types are defined). To retain the same functionality, these types now implement the `Rand` trait so they can be generated with a random seed from another random number generator. This allows the stdlib to use an OSRng to create seeded instances of these RNGs. * Rand implementations for `Box<T>` and `@T` were removed. These seemed to be pretty rare in the codebase, and it allows for libcore to not depend on liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not supported. If this is undesirable, librand can depend on liballoc and regain these implementations. * The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`, but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice structure now has a lifetime associated with it. cc #13851 [breaking-change]		2014-05-29 16:41:42 -07:00

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/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.
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, 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.
