[toolchain]
channel = "nightly"
components = [ "rustc", "cargo", "rust-src" ]
profile = "minimal"

flake.nix

nixpkgs-mozilla = {
    url = "github:mozilla/nixpkgs-mozilla";
    flake = false;
};

// ... 
pkgs = (import nixpkgs) {
    inherit system;
    overlays = [ (import nixpkgs-mozilla) ];
};

toolchain = (pkgs.rustChannelOf {
    rustToolchain = ./rust-toolchain.toml;
    sha256 = "sha256-vFu6RmeJsrTgIjNjNJrC+pVZh1fgr0wm7VX24RJQ14k=";
