Profpatsch and me are basically the only users of depot.users.Profpatsch.writers.rustSimple*. To pull in the odd dependency we usually use buildRustCrate which is rather convenient. However we've picked up the bad habit of inlining these in a let somewhere instead of managing them in a more central location although there has been an (unsuccesful) attempt at this in //users/Profpatsch/rust-crates.nix. This CL moves all buildRustCrate based derivations into third_party.rust-crates and deletes any duplicate derivations we have accumulated in the tree.
