rustworkx.PyDiGraph.insert_node_on_in_edges_multiple

PyDiGraph.insert_node_on_in_edges_multiple(node, ref_nodes, /)

Insert a node between a list of reference nodes and all their predecessors

This essentially iterates over all edges into the reference node specified in the ref_nodes parameter removes those edges and then adds 2 edges, one from the predecessor of ref_node to node and the other from node to ref_node. The edge payloads for the newly created edges are copied by reference from the original edge that gets removed.

Parameters:

  • node (int) – The node index to insert between

  • ref_node (int) – The reference node index to insert node between
