How sdevanathan96/rusty-redis works

rusty-redis is an in-memory, Redis-compatible RESP server. A client sends RESP commands through a connection; frames become parsed commands, which the keyspace task executes against the database and returns as RESP replies. Blocking list/stream operations and WATCH transactions are coordinated in the keyspace/connection layers. The graph preserves the documented command families and storage stages; some domain-handler and startup links rely on the README or SOURCE INDEX references rather than fully sampled implementations.

Main entry points: command.rs Command parsing and dispatch · db.rs Database and expiry · keyspace.rs Keyspace task · connection.rs Client connections
