Just Built: Oxide-Cache — A High-Performance LRU Cache in Rust!

I’m excited to share Oxide-Cache, a thread-safe, Least Recently Used (LRU) caching library built from scratch to handle high-concurrency workloads.

Fixed-capacity storage with O(1) access

Thread-safe implementation using Mutex and Arc

Automatic eviction of least recently used items

Support for custom expiration policies

Zero-dependency build for maximum portability

Building this project taught me a lot about memory layout, pointer safety in Rust, and how to implement complex data structures like doubly-linked lists without falling into 'borrow checker hell'. It’s wild to see how much faster a system becomes when you optimize the data retrieval layer.

If you’re curious about how caching works under the hood or want to see a practical example of interior mutability in Rust, I’d love for you to check it out!

Whether you're building a web server or a CLI tool, a solid cache is a game changer. Happy to discuss the logic if anyone's interested!
