Show HN: Tinykv – Minimal file-backed key-value store for Rust

I built tinykv because I kept reaching for simple persistent storage in Rust projects but found existing solutions either too complex (sled) or unmaintained (pickledb).

tinykv focuses on simplicity: JSON-based, serde-powered, with optional TTL. Perfect for CLI tools, game saves, config storage.

Would appreciate any feedback from the HN community!
