Function petgraph::algo::scc

pub fn scc<N, E, Ty, Ix>(g: &Graph<N, E, Ty, Ix>) -> Vec<Vec<NodeIndex<Ix>>> where Ty: EdgeType, Ix: IndexType

Compute the strongly connected components using Kosaraju's algorithm.

Return a vector where each element is an scc.

For an undirected graph, the sccs are simply the connected components.
