16/* Rust's build process has a few quirks :
17
18- It requires some patched in llvm that haven't landed upstream, so it
19 compiles its own llvm. This might change in the future, so at some
20 point we may be able to switch to nix's llvm.
21
22- The Rust compiler is written is Rust, so it requires a bootstrap
23 compiler, which is downloaded during the build. To make the build
24 pure, we download it ourself before and put it where it is
25 expected. Once the language is stable (1.0) , we might want to
26 switch it to use nix's packaged rust compiler.
27
28NOTE : some derivation depend on rust. When updating this, please make
29sure those derivations still compile. (racer, for example).
