Detailed Description

Cache top-level descriptor encapsulating the hash table root and capacity limit.

The cache enforces an upper bound (max_items) on the number of tracked entries. Insert helpers are expected to evict (or refuse) when the limit is exceeded (strategy defined in implementation; current behavior may be simple non-evicting if not yet implemented as a true LRU). The cache pointer holds the uthash root (NULL when empty).

Fields:

• max_items: Maximum number of entries allowed; 0 means "no explicit limit" if accepted by implementation.
• cache: uthash root pointer; NULL when the cache is empty.
