Oh no, it's all good... But I don't see "crates-xyz" (or just xyz) in
guix's packages.

   - https://packages.guix.gnu.org/search/?query=crates-xyz
   - https://packages.guix.gnu.org/search/?query=xyz


$ guix build -L ~/dotfiles/ rustscan
guix build: warning: failed to load '(guix packages rustscan)':
no code for module (gnu packages crates-xyz)


What is "crates-xyz" meant to do? And where is its definition?
