Racer - code completion for Rust
RACER = Rust Auto-Complete-er. A utility intended to provide Rust code completion for editors and IDEs. Maybe one day the 'er' bit will be exploring + refactoring or something.
This method requires Rust 1.5. Simply run:

Test on the command line:
racer complete std::io::B(should show some completions)
Emacs integration has been moved to a separate project: emacs-racer.
Gedit integration can be found here.
