/* Rust's build process has a few quirks :
- The Rust compiler is written is Rust, so it requires a bootstrap
compiler, which is downloaded during the build. To make the build
pure, we download it ourself before and put it where it is
expected. Once the language is stable (1.0) , we might want to
switch it to use nix's packaged rust compiler. This might not be possible
as the compiler is highly coupled to the bootstrap.
NOTE : some derivation depend on rust. When updating this, please make
sure those derivations still compile. (racer, for example).
