# 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: ```rust #[macro_use] extern crate version; // ... version!() // Returns something like "1.0.0" let ver : Version = FromStr::from_str( version!() ).unwrap(); ``` ## 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}` ).
