version

version is a very simple library who's job is to return the version of your crate if you're building with Cargo.

Usage:

#[macro_use]
extern crate version;

// ...

version!() // Returns something like "1.0.0"

let ver : Version = current();

Notes:

This only works if you're building with Cargo since the macro fetches the version digits from enviroment variables set by Cargo ( CARGO_PKG_VERSION_{MAJOR, MINOR, PATCH} ).
