The Base64 package previously had extremely basic functionality. It only suported the standard encoding character set, didn't support line breaks and always padded output. This commit makes it significantly more powerful. The FromBase64 impl now supports all of the standard variants of Base64. It ignores newlines,interprets '-' and '_' as well as '+' and '/' and doesn't require padding. It isn't incredibly pedantic and will successfully parse strings that are not strictly valid, but I don't think the extra complexity required to make it accept _only_ valid strings is worth it. The ToBase64 trait has been modified such that to_base64 now takes a base64::Config struct which contains the output format configuration. This currently includes the selection of character set (standard or url safe), whether or not to pad and an optional line break width. The package comes with three static Config structs for the RFC 4648 standard, RFC 4648 url safe and RFC 2045 MIME formats. The other option for configuring ToBase64 output would be to have one method with the configuration flags passed and other traits with default impls for the common cases, but I think that's a little messier. FromBase64 still kills the task if you pass it invalid input, which isn't particularly appropriate for a function into which you'll be passing unvalidated input. Would it be worth changing its signature to return a Result? |

The Rust Programming Language
This is a compiler for Rust, including standard libraries, tools and documentation.
Installation
The Rust compiler currently must be built from a tarball, unless you are on Windows, in which case using the installer is recommended.
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.
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.
To build from source you will also need the following prerequisite packages:
- 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
Assuming you're on a relatively modern *nix system and have met the prerequisites, something along these lines should work.
$ curl -O http://static.rust-lang.org/dist/rust-0.7.tar.gz
$ tar -xzf rust-0.7.tar.gz
$ cd rust-0.7
$ ./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.
