Description

This module provides a Map variant which uses the value's Monoid instance to accumulate conflicting entries when merging Maps.

While some functions mirroring those of Map are provided here for convenience, more specialized needs will likely want to use either the Newtype or Wrapped instances to manipulate the underlying Map.

mapKeysMonotonic :: forall k1 k2 a. (k1 -> k2) -> MonoidalMap k1 a -> MonoidalMap k2 a Source #

O(n). mapKeysMonotonic f s == mapKeys f s, but works only when f is strictly increasing (both monotonic and injective). That is, for any values x and y, if x < y then f x < f y and f is injective (i.e. it never maps two input keys to the same output key). The precondition is not checked. Semi-formally, we have:

and [x < y ==> f x < f y | x <- ls, y <- ls]
                    ==> mapKeysMonotonic f s == mapKeys f s
    where ls = keys s

This means that f maps distinct original keys to distinct resulting keys. This function has better performance than mapKeys.
