The <code>cargo</code> and <code>rustc</code> derivations provide the Rust toolchain in nixpkgs. An advantage of using nixpkgs is that it's dead simple and you get pinned versions, deterministic builds in nix-shell, etc. However, nixpkgs only maintains a single version of the Rust stable toolchain, so if you require a nightly toolchain or | The <code>cargo</code> and <code>rustc</code> derivations provide the Rust toolchain in nixpkgs. An advantage of using nixpkgs is that it's dead simple and you get pinned versions, deterministic builds in nix-shell, etc. However, nixpkgs only maintains a single version of the Rust stable toolchain, so if you require a nightly toolchain or switch between multiple toolchains then this approach may not be for you. | ||

The rustup tool is maintained by the Rust community and offers an interface to install and switch between Rust toolchains. In this scenario, rustup handles the "package management" of Rust toolchains and places them in <code>$PATH</code>. Nixpkgs offers rustup via the <code>rustup</code> derivation. More info on using rustup can be found on their official website: https://rustup.rs/. | The rustup tool is maintained by the Rust community and offers an interface to install and switch between Rust toolchains.
