Data.MapLike.Instances

Contents

Description

Defines MapLike instances declaration for standard data types

Synopsis

Documentation

class MapLike c k v | c -> k, c -> v where Source #

An abstract interface to the container which can store v indexed by k

Minimal complete definition

Methods

add :: k -> v -> c -> c Source #

Instances

MapLike (IntMap v) Int v Source #	Data.IntMap is usually more efficient that Data.Map if `k :: Int`
Instance details Defined in Data.MapLike.Instances Methods lookup :: Int -> IntMap v -> Maybe v Source # add :: Int -> v -> IntMap v -> IntMap v Source #
Ord k => MapLike (Map k v) k v Source #	Data.Map is a default implementation (not the fastest but well-known)
Instance details Defined in Data.MapLike.Instances Methods lookup :: k -> Map k v -> Maybe v Source # add :: k -> v -> Map k v -> Map k v Source #
