<commit_before><commit_msg>examples: single-threaded chat combinator example (#794)<commit_after>//! A chat server that broadcasts a message to all connections.
//!
//! This is a line-based server which accepts connections, reads lines from
//! those connections, and broadcasts the lines to all other connected clients.
//!
//! This example is similar to chat.rs, but uses combinators and a much more
//! functional style.
//!
//! Because we are here running the reactor/executor on the same thread instead
//! of a threadpool, we can avoid full synchronization with Arc + Mutex and use
//! Rc + RefCell instead. The max performance is however limited to a CPU HW
//! thread.
//!
//! You can test this out by running:
//!
//!     cargo run --example chat-combinator-current-thread
//!
//! And then in another window run:
//!
//!     cargo run --example connect 127.0.0.1:8080
//!
//! You can run the second command in multiple windows and then chat between the
//! two, seeing the messages from the other client as they're received. For all
//! connected clients they'll all join the same room and see everyone else's
//! messages.
