    edge_targets: Vec<N>,
}

Fields

node_starts: IndexVec<N, usize>

Maps from a given node to an index where the set of successors for that node starts. The index indexes into the edges vector. To find the range for a given node, we look up the start for that node and then the start for the next node (i.e., with an index 1 higher) and get the range between the two. This vector always has an extra entry so that this works even for the max element.
