immediately surrounding a node that is a terminating_scope (e.g. statements, looping forms) during which the destructors run (the destructors for temporaries from the execution of that node, that is). Introduced DestructionScopeData newtype wrapper around ast::NodeId, to preserve invariant that FreeRegion and ScopeChain::BlockScope carry destruction scopes (rather than arbitrary CodeExtents). Insert DestructionScope and block Remainder into enclosing CodeExtents hierarchy. Add more doc for DestructionScope, complete with ASCII art. Switch to constructing DestructionScope rather than Misc in a number of places, mostly related to `ty::ReFree` creation, and use destruction-scopes of node-ids at various calls to liberate_late_bound_regions. middle::resolve_lifetime: Map BlockScope to DestructionScope in `fn resolve_free_lifetime`. Add the InnermostDeclaringBlock and InnermostEnclosingExpr enums that are my attempt to clarify the region::Context structure, and that later commmts build upon. Improve the debug output for `CodeExtent` attached to `ty::Region::ReScope`. Loosened an assertion in `rustc_trans::trans::cleanup` to account for `DestructionScope`. (Perhaps this should just be switched entirely over to `DestructionScope`, rather than allowing for either `Misc` or `DestructionScope`.) ---- Even though the DestructionScope is new, this particular commit should not actually change the semantics of any current code.
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 Rust Programming Language.
- Enjoy!
Note: Windows users can read the detailed using Rust on Windows notes on the wiki.
Building from Source
-
Make sure you have installed the dependencies:
g++
4.7 orclang++
3.xpython
2.6 or later (but not 3.x)- 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 https://static.rust-lang.org/dist/rustc-nightly-src.tar.gz $ tar -xzf rustc-nightly-src.tar.gz $ cd rustc-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 toconfigure
. 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, andrustdoc
, the API-documentation tool. -
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.
# choose one based on platform
$ pacman -S mingw-w64-i686-toolchain
$ pacman -S mingw-w64-x86_64-toolchain
$ pacman -S base-devel
-
With that now start
mingw32_shell.bat
ormingw64_shell.bat
from where you installed MSYS2 (i.e.C:\msys
). Which one you choose depends on if you want 32 or 64 bit Rust. -
From there just navigate to where you have Rust's source code, configure and build it:
$ ./configure $ 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 and x86-64 (64-bit support added in Rust 0.12.0)
- 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.
Getting help and getting involved
The Rust community congregates in a few places:
- StackOverflow - Direct questions about using the language here.
- users.rust-lang.org - General discussion, broader questions.
- internals.rust-lang.org - For development of the Rust language itself.
- /r/rust - News and general discussion.
