Function iter_nodes

Expand description

Iterate on the nodes of the sub-graph rooted at start, in BFS order.

start is usually a single node id, passed as &[node], but can be a non-singleton slice or iterator of nodes, to avoid independently re-visiting shared sub-graphs from multiple starting points.

See NodeVisit documentation for performance considerations.

§Examples

let src = &[1, 2, 3];
for node in iter_nodes(graph, src) {
    println!("Visiting: {}", node);
}
let src = 1..4;
for node in iter_nodes(graph, src) {
    println!("Visiting: {}", node);
}
