//! Hello world server.

//! A simple client that connects to a mini-redis server, sets key "hello" with value "world",
//! and gets it from the server after
//!
//! You can test this out by running:
//!
//! cargo run --bin mini-redis-server
//!
//! And then in another terminal run:
//!
//! cargo run --example hello_world
