Description
Thanks for making this software, it's very useful.
Is it safe to call hashmap_delete while using hashmap_iter (or hashmap_scan)? Would this ever result in invalid pointers, or in some items being skipped by the iterator?
If it's not safe, how would you suggest implementing a "filter" function? Could it be added as a feature?

Research direction
Start by reading the hashmap_delete, hashmap_iter, and hashmap_scan APIs and their related tests, if present. Establish whether deletion during iteration is supported and what behavior a filter operation should guarantee. Done means the safety question is answered and any proposed filter scope and expected iteration behavior are clearly defined.
