How fool-mrrice/codecrafters-redis-rust works

This repository is a Rust Redis-compatible in-memory server. The principal workflow is a client sending RESP commands to the server, which dispatches commands to handlers and returns RESP responses backed by shared database state. The documented feature branches include strings, lists, Streams, blocking commands, transactions, expiry, RDB parsing, and replication. The README and excerpts support the main command path; implementation details for server networking and replication are not sampled, so those connections are left out or marked unverified.
