Module hashmap

An unordered map.

An immutable hash map using hash array mapped tries.

Most operations on this map are O(log_x n) for a suitably high x that it should be nearly O(1) for most maps. Because of this, it’s a great choice for a generic map as long as you don’t mind that keys will need to implement Hash and Eq.

Map entries will have a predictable order based on the hasher being used. Unless otherwise specified, this will be the standard RandomState hasher.
