Code browser for Rust?

Does anyone know of a Web-based code browser with crosslinking for Rust? For an example, see LXR and the Linux kernel highlighted with it. I could always fall back on Vim and Exuberant Ctags, but I haven't gotten the hang of searching a project inside Vim yet. Anything would be better than Github's code viewer.

/ - mozsearch ?

I…actually think that will do. DXR looks awesome -- thanks a lot!
