> Fenix provides the `minimal` , `default` , `complete` , and [`latest`](https://github.com/figsoda/fenix#the-latest-profile) [profile](https://rust-lang.github.io/rustup/concepts/profiles.html) of rust nightly toolchains, nightly version of [rust analyzer](https://rust-analyzer.github.io) and [its vscode extension](https://marketplace.visualstudio.com/items?itemName=matklad.rust-analyzer) with all components. It intends to be an alternative to [rustup](https://rustup.rs) and the rust overlay provided by [nixpkgs-mozilla](https://github.com/mozilla/nixpkgs-mozilla).
(Partly sharing so I can find this easier next time I need it again 🙂 )

Thanks!
For the uninitiated, how does it compare with Mozilla’s overlay?
