This is a simple Pop3 client that implements all of the features according to RFC 1939, written in Rust.
It is used in Dust-Mail to connect to Pop servers.
You can create a new session using the connect function or the connect_plain function.
connect expects a tls connector from the async-native-tls crate. In the future more tls options will be supported.
If you already have a connected socket, you can also create a new session using the new function.

let mut client = async_pop::connect(("pop.gmail.com", 995), "pop.gmail.com", &tls).await.unwrap();
client.login("example@gmail.com", "password").await.unwrap();
let bytes = client.retr(1).await.unwrap();
let message = parse_mail(&bytes).unwrap();
