SquidDev opened PR #4152 from feature/trap-hook to main:

Adds Store::epoch_deadline_callback. This accepts a callback which, when invoked, can mutate the store's contents. The callback can either return an error (in which case we trap) or return a delta which we'll use to set the new epoch deadline.

As discussed with @alexcrichton on Zulip. I'm not very happy with the tests here - happy to improve those if people have ideas.

It might be desirable to reimplement the trap and yield behaviours in terms of this callback. Happy to do that if preferred.

As a small nit, this can probably use ? to remove the error handling perhaps

As a small nit the leading &mut here can be removed

For symmetry with above this &mut can also be removed although you'll need to do let delta = *delta below I think
