A Toy Redis Server in Rust

Steps

Write a parser for redis protocol
Hack main to accept connection and return "Ok" always (no threads/concurrency), using raw TcpStream
- Should fool redis-cli
Run the above in a loop
Spawn a thread for each connection (maybe use mpsc channels?)
Parse Commands (only SET and GET) from Resp Array
- Make a HashMap based storage, and handle SET and GET
- Maybe generalize to parse more commands
Somehow use tokio event loops
Re-write protocols in tokio
