This is preliminary version of the Rust compiler.
Source layout:
rustc/ The self-hosted compiler
cargo/ The package manager
libcore/ The core library (imported and linked by default)
libstd/ The standard library (slightly more peripheral code)
rustllvm/ LLVM support code
rt/ The runtime system
rt/rust_*.cpp - The majority of the runtime services
rt/isaac - The PRNG used for pseudo-random choices in the runtime
rt/bigint - The bigint library used for the 'big' type
rt/uthash - Small hashtable-and-list library for C, used in runtime
rt/libuv - The library used for async IO in the runtime
rt/{sync,util} - Small utility classes for the runtime.
test/ Testsuite
test/compile-fail - Tests that should fail to compile
test/run-fail - Tests that should compile, run and fail
test/run-pass - Tests that should compile, run and succeed
test/bench - Benchmarks and miscellanea
Please be gentle, it's a work in progress.
