|
//! A basic chat application with logs demonstrating libp2p and the gossipsub protocol
|
|
//! combined with mDNS for the discovery of peers to gossip with.
|
|
//!
|
|
//! Using two terminal windows, start two instances, typing the following in each:
|
|
//!
|
|
//! ```sh
|
|
//! cargo run
|
|
//! ```
|
|
//!
|
|
//! Mutual mDNS discovery may take a few seconds. When each peer does discover the other
|
|
//! it will print a message like:
|
|
//!
|
|
//! ```sh
|
|
//! mDNS discovered a new peer: {peerId}
|
|
//! ```
|
|
//!
|
|
//! Type a message and hit return: the message is sent and printed in the other terminal.
|
|
//! Close with Ctrl-c.
|
|
//!
|
|
//! You can open more terminal windows and add more peers using the same line above.
|
|
//!
|
|
//! Once an additional peer is mDNS discovered it can participate in the conversation
|
|
//! and all peers will receive messages sent from it.
|
|
//!
|
|
//! If a participant exits (Control-C or otherwise) the other peers will receive an mDNS expired
|
|
//! event and remove the expired peer from the list of known peers.
