}

An event generated by ChannelManager which indicates a message should be sent to a peer (or broadcast to most peers). These events are handled by PeerManager::process_events if you are using a PeerManager.

Variants

SendAcceptChannel

Used to indicate that we've accepted a channel open and should send the accept_channel message provided to the given peer.

Fields of SendAcceptChannel

node_id: PublicKey

The node_id of the node which should receive this message

msg: AcceptChannel

The message which should be sent.

SendOpenChannel

Used to indicate that we've initiated a channel open and should send the open_channel message provided to the given peer.

Fields of SendOpenChannel

node_id: PublicKey

The node_id of the node which should receive this message

msg: OpenChannel

The message which should be sent.

SendFundingCreated

Used to indicate that a funding_created message should be sent to the peer with the given node_id.

Fields of SendFundingCreated

node_id: PublicKey

The node_id of the node which should receive this message

msg: FundingCreated

The message which should be sent.

SendFundingSigned

Used to indicate that a funding_signed message should be sent to the peer with the given node_id.

Fields of SendFundingSigned

node_id: PublicKey

The node_id of the node which should receive this message

msg: FundingSigned

The message which should be sent.

SendFundingLocked

Used to indicate that a funding_locked message should be sent to the peer with the given node_id.

Fields of SendFundingLocked

node_id: PublicKey

The node_id of the node which should receive these message(s)

msg: FundingLocked

The funding_locked message which should be sent.

SendAnnouncementSignatures

Used to indicate that an announcement_signatures message should be sent to the peer with the given node_id.

Fields of SendAnnouncementSignatures

node_id: PublicKey

The node_id of the node which should receive these message(s)

msg: AnnouncementSignatures

The announcement_signatures message which should be sent.

UpdateHTLCs

Used to indicate that a series of HTLC update messages, as well as a commitment_signed message should be sent to the peer with the given node_id.

Fields of UpdateHTLCs

node_id: PublicKey

The node_id of the node which should receive these message(s)

updates: CommitmentUpdate

The update messages which should be sent. ALL messages in the struct should be sent!

SendRevokeAndACK

Used to indicate that a revoke_and_ack message should be sent to the peer with the given node_id.

Fields of SendRevokeAndACK

node_id: PublicKey

The node_id of the node which should receive this message

msg: RevokeAndACK

The message which should be sent.

SendClosingSigned

Used to indicate that a closing_signed message should be sent to the peer with the given node_id.

Fields of SendClosingSigned

node_id: PublicKey

The node_id of the node which should receive this message

msg: ClosingSigned

The message which should be sent.

SendShutdown

Used to indicate that a shutdown message should be sent to the peer with the given node_id.

Fields of SendShutdown

node_id: PublicKey

The node_id of the node which should receive this message

msg: Shutdown

The message which should be sent.

SendChannelReestablish

Used to indicate that a channel_reestablish message should be sent to the peer with the given node_id.

Fields of SendChannelReestablish

node_id: PublicKey

The node_id of the node which should receive this message

msg: ChannelReestablish

The message which should be sent.

BroadcastChannelAnnouncement

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 call ChannelManager::broadcast_node_announcement to trigger a BroadcastNodeAnnouncement event. 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.

Fields of BroadcastChannelAnnouncement

msg: ChannelAnnouncement

The channel_announcement which should be sent.

update_msg: ChannelUpdate

The followup channel_update which should be sent.

BroadcastNodeAnnouncement

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

Fields of BroadcastNodeAnnouncement

msg: NodeAnnouncement

The node_announcement which should be sent.

BroadcastChannelUpdate

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

Fields of BroadcastChannelUpdate

msg: ChannelUpdate

The channel_update which should be sent.

HandleError

Broadcast an error downstream to be handled

Fields of HandleError

node_id: PublicKey

The node_id of the node which should receive this message

action: ErrorAction

The action which should be taken.

PaymentFailureNetworkUpdate

When a payment fails we may receive updates back from the hop where it failed. In such cases this event is generated so that we can inform the router of this information.

Fields of PaymentFailureNetworkUpdate

update: HTLCFailChannelUpdate

The channel/node update which should be sent to router
