This utility (rust-ctags) is intended for use with Exuberant Ctags. You can just clone this repo and then execution

> /path/to/rust-ctags src

and it will generate a TAGS file with the Rust language tags from src.

Note: the ctags definition is not perfect, but it tends to do the job. It should probably be extended to account for newer langauge features. PRs welcome! =)
