rustc-simple-version

The rustc-simple-version crate provides a simple constant that exposes the version of rustc used to compile your project.

use rustc_simple_version::RUSTC_VERSION;

println!("Built using {}", RUSTC_VERSION);

The main difference between this and rustc_version is that the latter is intended to be used as a build dependency for your build.rs, while this crate should be used at runtime.
