lrucache: a simple, pure LRU cache

[ bsd3, data, library ] [ Propose Tags ]

This package contains a simple, pure LRU cache, implemented in terms of Data.Map.

It also contains a mutable IO wrapper providing atomic updates to an LRU cache.

Version History:

  1. 1.1 - Add an additional modification function for AtomicLRUCache.

  2. 1.0.1 - Update containers constraint to allow containers from ghc-7

  3. 1 - Add a Functor instance for LRUCache. Add a generic modification function for AtomicLRUCache.

  4. 0 - Breaking API changes: 1) The newLRU smart constructor now makes the maximum size optional. 2) The delete function now returns the value removed, if one was. Additionally, a function was added to remove the least-recently used element in the LRU.

  5. 3 - Added a Show instance for LRU. (Requested by Ben Lee)

  6. 2.0.1 - Increase strictness slightly. Remove cabal target for test executable. (Just include test sources instead.)

  7. 2 - Added an Eq instance for LRU. Added strictness to eliminate space leaks in common use patterns.

  8. 1.1 - Add the Data.Cache.LRU.IO.Internal module. Clean up build warnings on GHC 6.12.1.

  9. 1.0.1 - Minor refactoring
