### Rust semantic completion
Completions and GoTo* within the current crate and its dependencies should work
out of the box with no additional configuration. For semantic analysis inclusive
of the standard library, you must have a local copy of
[the rust source][rust-src]. Additionally, a configuration is needed to tell
YouCompleteMe where to find it.
```viml
// In this example, the rust zip has been extracted to
// /usr/local/rust/rustc-1.5.0
let g:ycm_rust_src_path = '/usr/local/rust/rustc-1.5.0/src
```
### Semantic completion for other languages

[Jedi][], [Omnisharp][], [Gocode][], and [TSServer][] engines, respectively.
