Rust support

[iago-lito]

Hey, and thank you for this plugin which makes coding very comfortable :)

I have recently delved into the Rust book, and this languge definitely looks awesome. How hard would it be to add support for Rust Language?
(as far as syntax is concerned, it is kind of a classical curly-braces/semicolon language, but there are no actual classes to tag, only structs and traits)

This is it, thank you for support !
