Struct lightning::routing::network_graph::NetworkGraph [−][src]
pub struct NetworkGraph { /* fields omitted */ }
Expand description
Represents the network as nodes and channels between them
Implementations
Returns all known valid channels’ short ids along with announced channel info.
(C-not exported) because we have no mapping for BTreeMap
s
Returns all known nodes’ public keys along with announced node info.
(C-not exported) because we have no mapping for BTreeMap
s
Get network addresses by node id. Returns None if the requested node is completely unknown, or if node announcement for the node was never received.
(C-not exported) as there is no practical way to track lifetimes of returned values.
Creates a new, empty, network graph.

pub fn update_node_from_announcement<T: Verification>(
&mut self,
msg: &NodeAnnouncement,
secp_ctx: &Secp256k1<T>
) -> Result<(), LightningError>
For an already known node (from channel announcements), update its stored properties from a given node announcement.
You probably don’t want to call this directly, instead relying on a NetGraphMsgHandler’s RoutingMessageHandler implementation to call it indirectly. This may be useful to accept routing messages from a source using a protocol other than the lightning P2P protocol.
pub fn update_node_from_unsigned_announcement(
&mut self,
msg: &UnsignedNodeAnnouncement
) -> Result<(), LightningError>
pub fn update_node_from_unsigned_announcement(
&mut self,
msg: &UnsignedNodeAnnouncement
) -> Result<(), LightningError>
For an already known node (from channel announcements), update its stored properties from a given node announcement without verifying the associated signatures. Because we aren’t given the associated signatures here we cannot relay the node announcement to any of our peers.

Store or update channel info from a channel announcement.

If a chain::Access
object is provided via chain_access
, it will be called to verify
the corresponding UTXO exists on chain and is correctly-formatted.

pub fn update_channel_from_unsigned_announcement<C: Deref>(

) -> Result<(), LightningError> where

Store or update channel info from a channel announcement without verifying the associated signatures. Because we aren’t given the associated signatures here we cannot relay the channel announcement to any of our peers.

Close a channel if a corresponding HTLC fail was sent. If permanent, removes a channel from the local storage. May cause the removal of nodes too, if this was their last channel. If not permanent, makes channels unavailable for routing.
pub fn update_channel<T: Verification>(
&mut self,

) -> Result<(), LightningError>
pub fn update_channel<T: Verification>(
&mut self,
msg: &ChannelUpdate,
secp_ctx: &Secp256k1<T>
) -> Result<(), LightningError>
For an already known (from announcement) channel, update info about one of the directions of the channel.

For an already known (from announcement) channel, update info about one of the directions of the channel without verifying the associated signatures. Because we aren’t given the associated signatures here we cannot relay the channel update to any of our peers.
