@dvdplm That's right! |

| // Position the iterator after the `after` element | ||
| iter.next(); |

Could you explain how this works? Why calling next after seek returned an Err would position the iterator after the after?

So the else branch is actually when there has been no errors

Ah, right, thanks for clarifying that. So we assume that after is present in the db, otherwise this is not correct?

So in this context, after is either None or an address that is actually in DB.

I think this could be simplified by writing:
if let Err(e) = iter.next(after) {
trace!("...");
}Cause Err is no used later on anyway

Just an idea. To get "atomic" PRs, we can make parity-common repo a submodule of this repo. A submodule is pinned to a commit, so we can avoid always manually changing branches. (And it also makes browsing all ethereum-related code easier!)

What if we just specify a commit hash for parity-common? Should be easier to implement, and should be safe.

lgtm, please just fix remove branch = from .toml files :)

Hm, the error is used in the trace log, and |

ah, you are totally right! I confused seek with peek 🤦♂️ |
