Expand description

A vacant entry which has a key.

This is usually going to be created by some search by key, which was not present in the collection. When this occurs, the get_entry method should move the owned key into a vacant entry, or clone it.

this can be thought of as owning a K, ready to insert when given a corresponding value.
