[−][src]Enum petgraph::visit::Control

[−]
pub enum Control<B> {
    Continue,
    Prune,
    Break(B),
}
[−]

Control flow for depth_first_search callbacks.

Variants

Continue
[−]

Continue the DFS traversal as normal.

Prune
[−]

Prune the current node from the DFS traversal. No more edges from this node will be reported to the callback. A DfsEvent::Finish for this node will still be reported. This can be returned in response to any DfsEvent, except Finish, which will panic.

Break(B)
[−]

Stop the DFS traversal and return the provided value.
