LRU Cache
LRUCache is a Python package for in-memory caching using the LRU (Least Recently Used) eviction policy. Unlike Python’s built-in OrderedDict-based approach, this implementation uses a min-heap priority queue to track access times, providing efficient eviction of the least recently used entry when the cache reaches capacity.
Features
- Zero dependencies with pure Python, no external libraries
- Granular TTL (time-to-live) expiration per cache entry
- Optional thread-safe mode via
threading.RLock - Cache introspection methods: inspect capacity, TTL, and contents at runtime
- Decorator-based caching for function return values
Usage
LRUCache only works in Python version 3.10 and above, you can install it with :
pip install lruheap
or, with uv package manager to faster installation :
uv pip install lruheap
