A broadcast relay functionality.

Accepts openings to broadcasted committed values and faithfully relays them to all parties.

Implementations

impl BroadcastRelay

pub fn new(listen: Receiver<Message>, parties: Vec<Sender<Message>>) -> Self

Create a new broadcast relay.

pub fn run(&self)

Continuously await broadcast communication rounds.

A broadcast round starts with all parties sending commitment opening information to the broadcast relay. Once openings have been received by all parties, the relay starts distributing openings to all parties, sending every opening to every party, except the party where the opening came from.

If the receiving channel errors this must mean that all parties have shut down and dropped their copies of the sender. In this case the broadcast relay also shuts down.
