Just using `cargo build` will work as you've seen, but building a Nix package won't work right now. If you're still keeping up with this thread, though, I have code in this repository to build a copy of buck2 with Nix -- it's several weeks out of date at this point though: - https://github.com/thoughtpolice/buck2-nix/tree/main/buck/nix/buck2 https://github.com/thoughtpolice/buck2-nix/tree/main/buck/ni... You should mostly be able to just 'callPackage' that and have it work if you have rust-overlay applied. Check the corresponding 'flake.nix' if you need it. The prost issue with buildRustPackage is preventing an upgrade, so ideally the minor patches to prost can get upstreamed, but I need to (again) file a ticket about moving this along.
