Projected hash hash map over hash set.

Overview

Often when storing objects inside a hashmap, their keys are already contained inside them. It's more efficient to store every key exactly once..

Implementation

ProjectedHashMap is implemented over HashSet.

It's defined for pair <K, V>, user of this crate needs to implement Borrow<K> for V.
