If you're trying to reduce the build time in your Rust project, and you have read blog posts like this one by Matthias Endler, there's a chance that you are here to try using an alternative compiler that runs in parallel with rustc for every CI build: Cranelift, also called CG_CLIF.
Here is the original post by Jason Williams describing how cg_clif works.
This Github Action simply gives you an "interface" to use this alternative compiler in other Actions you may have.
PRs are welcomed.
