Makes things a little easier to debug and trace

Looks good! We can def merge pending tests + formatting...

Would be great to merge this! Let me know if you want a hand with the formatting?

Cargo has a slightly odd feature where it presumes ~ in requirements. So I pinned and pushed. Sorry we got bogged down a bit in the overhead on this one. The feature is nice!

Edit: @eitsupi looks like you need to give the "OK" on the changes[^1]

[^1]: maybe we shouldn't use this feature unless something is really important and won't get checked in tests (which this will), since it blocks until the original individual approves...

@max-sixty thank you for your help with this
