LruCache Build Status Coverage Status Go Report Card

This project is now archived, since httpcache.Cache is itself archived, and I haven't used this in years.

LruCache is a thread-safe, in-memory httpcache.Cache implementation that evicts the least recently used entries when a byte size limit or optional max age would be exceeded.

Using the included TwoTier wrapper, it could also be used as a small and fast cache for popular objects, falling back to a larger and slower cache (such as s3cache) for less popular ones.

Also see the godoc API documentation for LruCache or TwoTier.

Included are a test suite with close to 100% test coverage and a parallel benchmark suite that shows individual Set, Get, and Delete operations take under 400ns to complete.
