mini-telegram 0.1.17

//! Subscribe to a telegram channel example.
//!
//! A simple client that connects to a mini-telegram server, subscribes to "foo" and "bar" channels
//! and awaits messages published on those channels
//!
//! You can test this out by running:
//!
//!     cargo run --bin mini-telegram-server
//!
//! Then in another terminal run:
//!
//!     cargo run --example sub
//!
//! And then in another terminal run:
//!
//!     cargo run --example pub
