Enum DijkstraEvent

Source

pub enum DijkstraEvent<N, E, K> {
    Discover(N, K),

}

Expand description

A dijkstra search visitor event.

Variants§

§

Discover(N, K)

This is invoked when a vertex is encountered for the first time and it’s popped from the queue. Together with the node, we report the optimal distance of the node.

§

ExamineEdge(N, N, E)

This is invoked on every out-edge of each vertex after it is discovered.

§

EdgeRelaxed(N, N, E)

Upon examination, if the distance of the target of the edge is reduced, this event is emitted.

§

EdgeNotRelaxed(N, N, E)

Upon examination, if the edge is not relaxed, this event is emitted.

§

Finish(N)

All edges from a node have been reported.
