Enum petgraph::visit::Control

source · [−]

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

Expand description

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.
