Redox is a toy redis implementation in Rust.
Largely incomplete (still a toy so far), but some cool stuff
Redox implements Partial RESP parsing, which as I understand is not the most common way of implementing the parser. I am not sure if the official implementations use partial parsing. This allows for a fixed size buffer to be consumed and parsed into a partial state, so that the buffer can now be cleared and filled again to a fixed size, rather than throwing away all the parsing work, growing the buffer, and attempting to parse again. This probably has some benefits if you are trying to store humungous stuff into redis, (not benchmarked, could be wrong), but probably has a negligible impact on day to day perfomance. (Just fill out the buffer completely).
This was my first combinator parser though, and I thought partial parsing would be cool to attempt, which is really the only reason I built it. Rust's type system is incredibly expressive and helps reason about the parsing very clearly.
Important
Line 71 at main.rs (), you can see that the buffer is opened with a fixed length of 20. This is not sufficient for any parsing really. It's just set to a small value to flex my partial parser :p
No real other notable features. Only supported actions right now are SET, GET, ECHO, PING, and also expiry for the SET/GET. I plan to complete all stages, so will eventually add support for replication, persistence, and streams.
(Codecrafters is pretty cool btw)
