I didn't see a test case where the iterators are actually restored. Is there one? Perhaps it exists in ipld-eth-state-snapshot?

It happens in the TestBuilderSnapshot tests, via test_helpers.RunStateSnapshot. Although there's no explicit check for the file in these tests, I do see them getting restored.

Great! I see it now. I read that test, but I didn't put 2 and 2 together regarding the interrupt.

Yeah, a check for the file is even better, but you are right, practically speaking even the previous version of the test couldn't have succeeded if the file were not created and used.

Haha, it shouldn't and hasn't, but it's technically possible for someone to create an indexer of a different type and pass the wrong batch in. That would just panic otherwise, so the error is more to document the fact that this batch type is covariant with the indexer.

Do you recall why we passed err in to Submit() before? I have a vague memory buzzing in the back of my mind and I want to double check that there is no longer any reason.

Basically it was due to handling rollbacks and commit in the submit function, so it needed the error to check whether to rollback. By factoring the rollback out, we avoid that, but now the caller is responsible for it.

Which reminds me that I need to defer a rollback call from the scope of service.writeStateDiff - since the tx is returned from PushBlock.
