Classes

ArrivalOrderTracker<TKey>

Queue/index tracker that preserves first-seen ordering with O(1) add/remove by key. Useful for TTL sweeps that should process oldest entries first.

ExpiringKeyTracker<TKey>

Queue/index tracker for expiring keyed entries. Uses head-first sweeps to avoid full dictionary enumeration under heavy load.

LastSeenCacheTracker<TKey, TValue>

Queue/index tracker for key-value caches whose entries expire by last-seen timestamp. Optimized for high-frequency touch and bounded head-first TTL sweeps.
