Description

InsOrdHashMap is like HashMap, but it folds and traverses in insertion order.

This module interface mimics Data.HashMap.Strict, with some additions.

The union of two maps. If a key occurs in both maps, the provided function (first argument) will be used to compute the result.

Ordered traversal will go thru keys in the first map first.

valid :: InsOrdHashMap k v -> Bool Source #

Test if the internal map structure is valid.
