Access to git version info in builds

help
1

Are there standard ways to get info such as the current Git revision ID into an executable during the cargo build process? There's CARGO_PKG_VERSION, but that's from Cargo.toml, not from Git.
The info you get from "git describe" would be fine as a "build ID".

(Yes, I could write a build script to run "git describe", but this seems like something that would already be available.)

The git_version crate provides macros that can query this for you during the build: git_version - Rust

Oh, that's great.

I didn't know you could cause a program to run at compile time without a build script.
