Trait PathSelector

pub trait PathSelector<CW, W = U256>
where
    CW: EdgeWeighting<W>,
    W: Default + Add<W, Output = W>,
{
    // Required method
    fn select_path(
        &self,
        graph: &ChannelGraph,
        source: Address,
        destination: Address,
        min_hops: usize,
        max_hops: usize,
    ) -> Result<ChannelPath>;

    // Provided method
    fn select_auto_path(
        &self,
        graph: &ChannelGraph,
        destination: Address,
    ) -> Result<ChannelPath> { ... }
}

Trait for implementing custom path selection algorithm from the channel graph.

Required Methods

fn select_path( &self, graph: &ChannelGraph, source: Address, destination: Address, min_hops: usize, max_hops: usize, ) -> Result<ChannelPath>

Select path of maximum max_hops from source to destination in the given channel graph. NOTE: the resulting path does not contain source but does contain destination. Fails if no such path can be found.

Provided Methods

fn select_auto_path( &self, graph: &ChannelGraph, destination: Address, ) -> Result<ChannelPath>

Constructs a new valid packet Path from self and the given destination. This method uses INTERMEDIATE_HOPS as the maximum number of hops.
