Project roadmap and task tracking for the nfx-lrucache library.

Todo

• Add optional capacity limits by memory (bytes) in addition to item count

• Expose runtime metrics (hits, misses, evictions, average latency)

• Add an eviction observer callback API for resource cleanup

• Stress-test thread-safety with sanitizers (ASan, TSan, UBSan) in CI

• Add optional lock-striping or sharded caches for lower contention

• Consider std::shared_mutex for read-heavy workloads (reduce lock contention)

• Add set() method for explicit cache insertion without factory function

• Add contains() method for existence check without value retrieval

• Add iterator support for cache traversal in LRU order

• Make MAX_CLEANUP_PER_CYCLE configurable and optionally adaptative (currently hardcoded to 10, may cause memory bloat in high-churn scenarios)

• Add adaptive cleanup strategy (clean more entries when expiration rate is high)

• Add usage examples for high-concurrency scenarios

• Add memory profiling benchmarks
