  let
    mozilla = import (builtins.fetchTarball https://github.com/mozilla/nixpkgs-mozilla/archive/master.tar.gz);
    nixpkgs = import <nixpkgs> { overlays = [ mozilla ]; };
  
    rustStable = (nixpkgs.rustChannelOf { date = "2021-03-25"; channel = "stable"; }).rust.override {
      extensions = [
        "clippy-preview"
        "rustfmt-preview"
        "rust-analysis"
        "rust-std"
        "rustc-dev"
        "rust-src"
      ];
    };
  
  in
  with nixpkgs;
  
  mkShell {
    buildInputs = [
      rustStable
    ];
  
    RUST_BACKTRACE = 1;
