[Nix-dev] Why does my system rebuild rustc and cargo?

[Matthias Beyer]

Sure:

    { pkgs ? (import <nixpkgs> {}) }:

    let
      env = with pkgs.rustUnstable; [
        rustc
        cargo
      ];
    in

    pkgs.stdenv.mkDerivation rec {
        name = "someproject";
        src = ./.;
        version = "0.0.0";

        buildInputs = [ env ];

    }

in my default.nix in the project repository I'm doing my rust foo in.
change `rustUnstable` to `rustPlatform` and it recompiles the things.

Maybe I'm just using a deprecated way of entering my nix-shell?
