@hackage hashmap1.1.0

Persistent containers HashMap and HashSet.

An implementation of persistent HashMap and HashSet on top of Data.IntMap.IntMap and Data.IntSet.IntSet, with very similar API. It uses Hashable class from the hashable package for hashing.

The HashMap key value is an Data.IntMap.IntMap indexed by the hash value, containing Data.Map.Map key value for all keys with the same hash value.

The HashSet elem is an Data.IntMap.IntMap indexed by the hash value, containing Data.Set.Set elem for all elements with the same hash value.
