Use wasm32-unknown-unknown

[flosse]

I'm sorry for bothering you but how I can get the wasm32-unknown-unknown target in an overlay?

edit: I managed to do this now in my shell.nix:

let
  fenix_overlay = import "${fetchTarball "https://github.com/nix-community/fenix/archive/main.tar.gz"}/overlay.nix";
  pkgs = import <nixpkgs> { overlays = [ fenix_overlay ]; };
  fenix = pkg.fenix;
  rust_stable = fenix.stable;
  rust_targets = with fenix.targets; [
    wasm32-unknown-unknown.stable.rust-std
    x86_64-unknown-linux-musl.stable.rust-std
  ];
  rust = with rust_stable; (fenix.combine [
    rustc
    cargo
    clippy
    rustfmt
    rust_targets
  ]);
in
  with pkgs;
  mkShell {
    buildInputs = [
      rust
      cmake
      pkgconfig
    ];
}

You got it!

Do note that it is recommended to flatten the list, as rust_targets is a list itself
