Code §

git sha as string in code §

Useful for distribution, to report what revision was built. In build.rs:

use std::process::Command;
fn main() {
    let output = Command::new("git").args(["rev-parse", "HEAD"]).output();
 
    let sha = match output {
        Ok(sha) => String::from_utf8(sha.stdout).unwrap(),
        Err(_) => String::from("NO_GIT"),
    };
 
    println!("cargo:rustc-env=GIT_HASH={}", sha);
}

Usage:

const SHA: &str = env!("GIT_HASH");
