Uses W-TinyLFU eviction that dynamically adapts to access patterns, achieving excellent hit ratios as demonstrated in benchmarks with distributions like zipf and s3.

Implements hierarchical timer wheels to automatically remove expired entries with minimal performance overhead, ensuring timely cleanup.

Supports Go generics for type-safe caching of any key-value types, providing a clean and idiomatic interface that reduces boilerplate.

Allows saving and restoring cache state via Gob encoding, useful for stateful applications that need to maintain cache across restarts, though with versioning caveats.
