Detailed Description

This file contains slot types that are supposed to be used with blender::Map.

Every slot type has to be able to hold a value of type Key, a value of type Value and state information. A map slot has three possible states: empty, occupied and removed.

When a slot is occupied, it stores instances of type Key and Value.

A map slot type has to implement a couple of methods that are explained in SimpleMapSlot. A slot type is assumed to be trivially destructible, when it is not in occupied state. So the destructor might not be called in that case.

Possible Improvements:

• Implement slot type that stores the hash.
