bors 47c9a35747 auto merge of #10830 : alexcrichton/rust/spsc-queue, r=brson This pull request completely rewrites std::comm and all associated users. Some major bullet points * Everything now works natively * oneshots have been removed * shared ports have been removed * try_recv no longer blocks (recv_opt blocks) * constructors are now Chan::new and SharedChan::new * failure is propagated on send * stream channels are 3x faster I have acquired the following measurements on this patch. I compared against Go, but remember that Go's channels are fundamentally different than ours in that sends are by-default blocking. This means that it's not really a totally fair comparison, but it's good to see ballpark numbers for anyway ``` oneshot stream shared1 std 2.111 3.073 1.730 my 6.639 1.037 1.238 native 5.748 1.017 1.250 go8 1.774 3.575 2.948 go8-inf slow 0.837 1.376 go8-128 4.832 1.430 1.504 go1 1.528 1.439 1.251 go2 1.753 3.845 3.166 ``` I had three benchmarks: * oneshot - N times, create a "oneshot channel", send on it, then receive on it (no task spawning) * stream - N times, send from one task to another task, wait for both to complete * shared1 - create N threads, each of which sends M times, and a port receives NM times. The rows are as follows: `std` - the current libstd implementation (before this pull request) * `my` - this pull request's implementation (in M:N mode) * `native` - this pull request's implementation (in 1:1 mode) * `goN` - go's implementation with GOMAXPROCS=N. The only relevant value is 8 (I had 8 cores on this machine) * `goN-X` - go's implementation where the channels in question were created with buffers of size `X` to behave more similarly to rust's channels.		2013-12-17 01:16:43 -08:00

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-0.8.tar.gz
 $ tar -xzf rust-0.8.tar.gz
 $ cd rust-0.8
```
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.
