//! ## A library for parsing byte data streams implemented according to RFC 1939.
//! ###### POP3 Command Summary
//！ Minimal POP3 Commands:
//！
//！ USER name valid in the AUTHORIZATION state
//！ PASS string
//！ QUIT
//！
//！ STAT valid in the TRANSACTION state
//！ LIST [msg]
//！ RETR msg
//！ DELE msg
//！ NOOP
//！ RSET
//！ QUIT
//！
//！ Optional POP3 Commands:
//！
//！ APOP name digest valid in the AUTHORIZATION state
//！
//！ TOP msg n valid in the TRANSACTION state
//！ UIDL [msg]
//! ##### Usage
//! All commands and reponses are categorized into three sections:
//! AUTHORIZATION, TRANSACTION and UPDATE.
//!
//! ###### Command Examples
//! ```rust
//! use rfc1939::authorization::command::*;
//! use rfc1939::transaction::command::*;
//! use rfc1939::types::command::*;
//!
//! # fn main() {
//! assert_eq!(user(b"USER name\r\n").unwrap(), User { name: b"name" });
//! assert_eq!(pass(b"PASS pwd\r\n").unwrap(), Pass { string: b"pwd" });
//! assert_eq!(
//! apop(b"APOP mrose c4c9334bac560ecc979e58001b3e22fb\r\n").unwrap(),
//! Apop {
//! name: b"mrose",
//! digest: b"c4c9334bac560ecc979e58001b3e22fb"
//! }
//! );
//! assert_eq!(stat(b"stat\r\n").unwrap(), Stat);
//! assert_eq!(list(b"LIST 2222\r\n").unwrap(), List { msg: Some(2222) });
//! assert_eq!(retr(b"RETR 1\r\n").unwrap(), Retr { msg: 1 });
//! assert_eq!(dele(b"DELE 1\r\n").unwrap(), Dele { msg: 1 });
//! assert_eq!(noop(b"NOOP\r\n").unwrap(), Noop);
//! assert_eq!(rset(b"RSET\r\n").unwrap(), Rset);
//! assert_eq!(top(b"TOP 1 10\r\n").unwrap(), Top { msg: 1, n: 10 });
//! assert_eq!(uidl(b"UIDL 1\r\n").unwrap(), Uidl { msg: Some(1) });
//! # }
//! ```
//! ###### Response Example
//! ```rust
//! use rfc1939::transaction::response::retr;
//! use rfc1939::types::response::Retr;
//! use rfc1939::common::StatusIndicator;
//!
//! # fn main() {
//! assert_eq!(
//! retr(b"+OK 120 octets\r\n<the POP3 server sends the entire message here>\r\n.\r\n")
//! .unwrap(),
//! Retr {
//! status_indicator: StatusIndicator::OK,
//! message: Some(b"<the POP3 server sends the entire message here>"),
//! information: b"120 octets"
//! }
//! );
//! # }
//! ```
// State
