Description

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

Synopsis

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

Methods

showsPrec :: Int -> PatchMap k v -> ShowS #

show :: PatchMap k v -> String #

showList :: [PatchMap k v] -> ShowS #

Ord k => Semigroup (PatchMap k v) Source #

a <> b will apply the changes of b and then apply the changes of a. If the same key is modified by both patches, the one on the left will take precedence.
