lfudacaching-0.1.0.0: lfudacaching.cabal

cabal-version: 3.0
name:          lfudacaching
version:       0.1.0.0
synopsis:      Pure LFUDA, GDSF, and LFU cache implementations
description:
  Pure, immutable cache with three eviction policies:
  .
  * __LFUDA__ — Least Frequently Used with Dynamic Aging
  * __GDSF__ — Greedy Dual-Size Frequency
  * __LFU__ — Least Frequently Used
  .
  All operations are /O(log n)/ in the number of cached entries, backed by a
  hash-priority search queue.
