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.
