My apologies, this was all partly my fault. I do have the old source lying
around, diffing the two (attached) reveals that the changelog and one source
file actually changed.

A bit more detailed context:
The rust project makes pre-release sources available for testing ahead of
the formal release, and the process is meant to shake out any potential bugs.
I tested with the prerelease build originally, and after the real release
came out I updated the package URL to the formal release and immediately
rebuilt successfully.

I'm not 100% sure if maybe guix reused the cached tarball I had from earlier,
or whether the prerelease source was immediately upgraded to the formal release
and fixed shortly after. (I did try rebuilding right before pushing the change
out which succeeded with no changes, which I'm guessing is because guix did
not redownload the tarball and why I didn't notice the hash mismatch).
