A map that creates a random handle on insertion to use when retrieving.
The raison d'être for this map is:
-
You want to put something in a map, but you have no key. Means you do not want to use a
HashMaporBTreeMap. -
You want to forget the details of what you put in to later retrieve it with a simple handle, and you are not interested in how many equal objects you insert. Means you do not want to use a
HashSetorHashMultiSet. -
You want a persistent handle to refer to the item you put in the map. Means you do not want to use a
Vec.
The implementation uses a HashMap that does not actually hash. The
contained HashMap can be borrowed (.as_hash_map()), so all HashMap
functions that do not change the map are at your disposal.
