//! Ping example
//!
//! See ../src/tutorial.rs for a step-by-step guide building the example below.
//!
//! In the first terminal window, run:
//!
//! ```sh
//! cargo run --example ping --features=full
//! ```
//!
//! It will print the PeerId and the listening addresses, e.g. `Listening on
//! "/ip4/0.0.0.0/tcp/24915"`
//!
//! In the second terminal window, start a new instance of the example with:
//!
//! ```sh
//! cargo run --example ping --features=full -- /ip4/127.0.0.1/tcp/24915
//! ```
//!
//! The two nodes establish a connection, negotiate the ping protocol
//! and begin pinging each other.
