Module documentation for 0.5.1.1

This version can be pinned in stack with:partial-semigroup-0.5.1.1@sha256:ba9e96aeedfc643e089a1273064f358a5c300b134595ef429367df8ee65eb7c9,5114

A partial semigroup is like a semigroup, but the operator is partial. We represent this in Haskell as a total function (<>?) :: a -> a -> Maybe a.

The partial-semigroup-hedgehog companion package provides support for checking the partial semigroup associativity axiom using the hedgehog package.
