[Feature Request] Target for Rust Programming Language

I propose we have a target for Rust Programming Language since:

1. Rust has finally delivered stable release last year (currently version 1.16).
2. Rust has attracted more and more engineers recent years.

Rust has become a mature programming language with the constant effort from Mozilla. The I haven't found any good parser generators in the Rust world yet. Hopefully, ANTLR can be one.
