pub struct ChannelPath { /* private fields */ }Expand description
Represents an on-chain path in the ChannelGraph.
This path is never allowed to be empty and is always constructed from
Addresses that must be known to have open channels between them (at the time of construction).
This path is not useful for transport, because it does never contain the last hop
to the destination (which does not require and open channel).
To make it useful for transport, it must be converted to a TransportPath via ChannelPath::into_path<R>.
The ChannelPath does not allow simple loops (same adjacent hops)
Implementations§
Source§impl ChannelPath
impl ChannelPath
Sourcepub fn new(hops: Vec<Address>, graph: &ChannelGraph) -> Result<Self>
pub fn new(hops: Vec<Address>, graph: &ChannelGraph) -> Result<Self>
Creates a new path by validating the list of addresses using the channel graph.
The given list of hops must not contain the sender node as the first entry,
since this node is always assumed to be the sender.
The list of hops also must not contain the destination, because an open
channel is not required for the last hop.
Sourcepub async fn into_path<R: HoprDbResolverOperations>(
self,
resolver: &R,
destination: Address,
) -> Result<TransportPath>
pub async fn into_path<R: HoprDbResolverOperations>( self, resolver: &R, destination: Address, ) -> Result<TransportPath>
Resolves this on-chain ChannelPath into the off-chain TransportPath and adds the final hop
to the given destination (which does not require an open channel).
The given resolver is used for the mapping between PeerIds and Addresses.
