Show HN: Cachekit – High performance caching policies library in Rust

Summary

cachekit High-performance cache policies and tiered caching primitives for Rust systems with optional metrics and benchmarks. Overview CacheKit is a Rust library that provides: High-performance cache replacement policies (e.g., FIFO , LRU , LRU-K ). , , ). Tiered caching primitives to build layered caching strategies. Optional metrics and benchmark harnesses. A modular API suitable for embedding in systems where control over caching behavior is critical. This crate is designed for systems programming, microservices, and performance-critical applications. Features Policy implementations optimized for performance and predictability. Backends that support both in-memory and composite cache strategies. Optional integration with metrics collectors (e.g., Prometheus/metrics crates). Benchmarks to compare policy performance under real-world workloads. Idiomatic Rust API with no_std compatibility where appropriate.
