Enum petgraph::visit::DfsEvent [−][src]
pub enum DfsEvent<N> { Discover(N, Time), TreeEdge(N, N), BackEdge(N, N), CrossForwardEdge(N, N), Finish(N, Time), }
A depth first search (DFS) visitor event.
Variants
Discover(N, Time)
An edge of the tree formed by the traversal.
An edge to an already visited node.
A cross or forward edge.
For an edge (u, v), if the discover time of v is greater than u, then it is a forward edge, else a cross edge.
Finish(N, Time)
All edges from a node have been reported.
