Also fixed all conflicting calls of the old functions in the rest of the codebase. The set of string conversion functions for each float type now consists of those items: - to_str(), converts to number in base 10 - to_str_hex(), converts to number in base 16 - to_str_radix(), converts to number in given radix - to_str_exact(), converts to number in base 10 with a exact number of trailing digits - to_str_digits(), converts to number in base 10 with a maximum number of trailing digits - implementations for to_str::ToStr and num::ToStrRadix - from_str(), parses a string as number in base 10 including decimal exponent and special values - from_str_hex(), parses a string as a number in base 16 including binary exponent and special values - from_str_radix(), parses a string as a number in a given base excluding any exponent and special values - implementations for from_str::FromStr and num::FromStrRadix
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-0.5.tar.gz
$ tar -xzf rust-0.5.tar.gz
$ cd rust-0.5
$ ./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 cargo
, the Rust package manager.
