Module rustc_ap_rustc_data_structures::graph::scc

Routine to compute the strongly connected components (SCCs) of a graph.

Also computes as the resulting DAG if each SCC is replaced with a node in the graph. This uses Tarjan’s algorithm that completes in O(n) time.

Structs

Sccs	Strongly connected components (SCC) of a graph. The type N is the index type for the graph nodes and S is the index type for the SCCs. We can map from each node to the SCC that it participates in, and we also have the successors of each SCC.
