Data.Patch.Map

Patches on Map that consist only of insertions (including overwrites) and deletions

Documentation

newtype PatchMap k v

A set of changes to a Map. Any element may be inserted/updated or deleted. Insertions are represented as values wrapped in Just, while deletions are represented as Nothings
