Used to indicate that a channel_announcement and channel_update should be broadcast to all peers (except the peer with node_id either msg.contents.node_id_1 or msg.contents.node_id_2).

Note that after doing so, you very likely (unless you did so very recently) want to broadcast a node_announcement (e.g. via PeerManager::broadcast_node_announcement). This ensures that any nodes which see our channel_announcement also have a relevant node_announcement, including relevant feature flags which may be important for routing through or to us.

Used to indicate that a node_announcement should be broadcast to all peers.

Fields

msg: NodeAnnouncement

The node_announcement which should be sent.

SendChannelUpdate

Used to indicate that a channel_update should be sent to a single peer. In contrast to Self::BroadcastChannelUpdate, this is used when the channel is a private channel and we shouldn’t be informing all of our peers of channel parameters.

Fields

node_id: PublicKey

The node_id of the node which should receive this message

msg: ChannelUpdate

The channel_update which should be sent.
