Language.Haskell.TH.Desugar.OMap.Strict

Contents

Description

An OMap behaves much like a Map, with all the same asymptotics, but also remembers the order that keys were inserted.

This module offers a simplified version of the Data.Map.Ordered.Strict API that assumes left-biased indices everywhere and uses a different Semigroup instance (the one in this module uses (<>) = union) and Monoid instance (the one in this module uses mappend = union).

Synopsis

Documentation

newtype OMap k v Source #

An ordered map whose insertPre, insertPost, intersection, intersectionWithKey, union, and unionWithKey operations are biased towards leftmost indices when when breaking ties between keys.
