class SimpleCache[A, B] extends Cache[A, B]
A simple, thread-safe Cache implementation based on trie maps.
Operations are atomic and allow concurrent access.
Once in the cache, values do not expire and are never released,
making this implementation not recommended when memory efficiency is of concern.
- A
 the type of the keys used to store and retrieve values
- B
 the type of the values stored in this cache
