Assert offset type in `DispatchScan[ByKey]` to be unsigned and at least 4 bytes #3992

bernhardmgruber · 2025-03-03T20:39:29Z

DispatchScan[ByKey] should only be instanted with unsigned types. This was a result of the large offset support benchmarking by @elstehle. #3111 updated the documentation accordingly, but we could not add an assertion ensuring it, because users may instantiate the dispatcher themselves.
