Data.Patch.Map

Description

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

Synopsis

newtype PatchMap k v = PatchMap {
- unPatchMap :: Map k (Maybe v)
}
patchMapNewElements :: PatchMap k v -> [v]
patchMapNewElementsMap :: PatchMap k v -> Map k v

Documentation

newtype PatchMap k v Source #

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

Constructors
