Rust winit XKBNotFound

Help

Hey, I’m trying to start learning Vulkan and I’m using ash.

This is the devshell I’m using. flake.nix:

{
  inputs = {
    utils.url = "github:numtide/flake-utils";
  };
  outputs = { self, nixpkgs, utils }: utils.lib.eachDefaultSystem (system:
    let
      pkgs = nixpkgs.legacyPackages.${system};
    in
    {
      devShell = pkgs.mkShell {
        buildInputs = with pkgs; [
            cargo
            vulkan-loader
        ];
      };
    }
  );
}

The examples build with this, but I get this error when I try to start the binary.

Error: Os(OsError { line: 80, file: "/home/codebam/.cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.15/src/platform_impl/linux/wayland/event_loop/mod.rs", error: WaylandError(Connection(NoWaylandLib)) })

What do I need to change in my flake.nix so winit can find libwayland?

Okay so I figured it out, another error now.

New flake.nix:

{
  inputs = {
    utils.url = "github:numtide/flake-utils";
  };
  outputs = { self, nixpkgs, utils }: utils.lib.eachDefaultSystem (system:
    let
      pkgs = nixpkgs.legacyPackages.${system};
    in
    {
      devShell = pkgs.mkShell {
        buildInputs = with pkgs; [
            cargo
            vulkan-loader
        ];

      LD_LIBRARY_PATH="${pkgs.wayland}/lib";
      };
    }
  );
}

New error:
