storekey - Rust

Binary serialization library for Rust values which preserves lexicographic sort order. Order-preserving encoding is useful for creating keys for sorted key-value stores with byte string typed keys, such as leveldb and sled.

arc_swap - Rust

Making `Arc` itself atomic

fjall - Rust

Fjall is a log-structured embeddable key-value storage engine written in Rust. It features:

candystore - Rust

A fast (blazingly, of course), persistent, in-process key-value store that relies on a novel sharding algorithm. Since Candy does not rely on log-structured merge (LSM) trees or B-Trees, no journal/WAL is needed and IOs go directly to file.

quick_cache - Rust

Lightweight, high performance concurrent cache. It allows very fast access to the cached items with little overhead compared to a plain concurrent hash table. No allocations are ever performed unless the cache internal state table needs growing (which will eventually stabilize).
