imcache

imcache has no external dependencies, ensuring easy integration into Go projects without third-party package bloat, as highlighted in its README.

Leverages Go's generics for type-safe caching, allowing compile-time checks and eliminating the need for manual type assertions with interface{}.

Supports absolute, sliding, and date-based expiration, providing fine-grained control over cache entry lifetimes, as detailed in usage examples.

Implements sharding to distribute cache entries, reducing lock contention and improving parallel performance, evidenced by benchmarks in the README.

Offers multiple eviction policies (LRU, LFU, random) and callbacks for eviction events, enabling sophisticated cache management.
