In reply to @accelbread:matrix.org
do you know which subset of files is being picked up?
ah

one thing you can try to debug is set:

{
  inputs.flakelight-rust.url = "github:accelbread/flakelight-rust";
  outputs = { flakelight-rust, ... }:
    flakelight-rust ./. ({ lib, outputs, ... }: {
      fileset = ./.;
      outputs.test = lib.fileset.toList outputs.fileset;
    });
}

and nix eval .#test

doesn't seem like fileset is being honoured/evaluated correctly when I'm setting it like so:

  outputs = { flakelight, flakelight-rust, devenv, ... }@inputs:
    flakelight ./. ({ pkgs, lib, outputs, ... }: {
      imports = [ flakelight-rust.flakelightModules.default ];
      systems = lib.systems.flakeExposed;
      fileset = ./.;

tried mkForceing it in case, that didn't work either

hmm, okay, still no luck - every time the source tree is the same, even with inherit src here:

package = { craneLib, cargoArtifacts, defaultMeta }:
        craneLib.buildPackage {
          inherit src;  # <-- here
          inherit cargoArtifacts;
          doCheck = false;
          strictDeps = true;
          meta = defaultMeta;
        };
