What we now do is to create a region variable for each & expression (and also each borrow). The lifetime of this variable will be checked by borrowck to ensure it is not greater than the lifetime of the underlying data. This both leads to shorter lifetimes in some cases but also longer in others, such as taking the address to the interior of unique boxes tht are rooted in region pointers (e.g., returning a pointer to the interior of a sendable map). This may lead to issue #2977 if the rvalue is not POD, because we may drop the data in trans sooner than borrowck expects us to. Need to work out precisely where that fix ought to occur.
The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Installation
The Rust compiler is slightly unusual in that it is written in Rust and therefore must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require that:
-
You are connected to the internet, to fetch snapshots.
-
You can at least execute snapshot binaries of one of the forms we offer them in. Currently we build and test snapshots on:
- Windows (7, server 2008 r2) x86 only
- Linux 2.6.x (various distributions) x86 and x86-64
- OSX 10.6 ("Snow leopard") or 10.7 ("Lion") x86 and x86-64
You may find other platforms work, but these are our "tier 1" supported build environments that are most likely to work. Further platforms will be added to the list in the future via cross-compilation.
To build from source you will also need the following prerequisite packages:
- g++ 4.4 or clang++ 3.x
- python 2.6 or later
- perl 5.0 or later
- gnu make 3.81 or later
- curl
Assuming you're on a relatively modern Linux/OSX system and have met the prerequisites, something along these lines should work:
$ tar -xzf rust-0.3.tar.gz
$ cd rust-0.3
$ ./configure
$ make && make install
When complete, make install will place the following programs into /usr/local/bin:
- rustc, the Rust compiler
- rustdoc, the API-documentation tool
- cargo, the Rust package manager
In addition to a manual page under /usr/local/share/man and a set of host and target libraries under /usr/local/lib/rustc.
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.
