git-build-version

Makes it easy to include a version (as provided by git describe) in your crate. For example:

In Cargo.toml:

[package]
name = "my-lovely-package"
# ...
build = "build.rs"

[build-dependencies]
git-build-version = "*"

In build.rs:

extern crate git_build_version;

const PACKAGE_TOP_DIR : &'static str = ".";

fn main() {
    git_version::write_version(PACKAGE_TOP_DIR).expect("Saving git version");
}

This will write out a file named version.rs that can be included into your source as follows. Eg: in your src/main.rs:

include!(concat!(env!("OUT_DIR"), "/version.rs"));

fn main() {
    println!("Version: {}", VERSION);
}
