Crate vergen

Defines the vergen function.

vergen when used in conjunction with the build script support from cargo, generates a file in OUT_DIR (defined by cargo) with three functions defined (now, sha, and semver). This file can then be use with include! to pull the functions into your source for use.

Example Cargo.toml

[package]
build = "build.rs"

[build-dependencies]
vergen = "*"

Example build.rs

// build.rs
extern crate vergen;

use vergen::vergen;

fn main() {
    vergen();
}

Example Usage

extern crate vergen;

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

fn main() {
    version();
}

// Example version function
fn version() -> String {
   format!("{} {} blah {}", now(), sha(), semver())
}
