Enum charcoal::traversal::VisitorDirection

pub enum VisitorDirection<C: Clone + Debug + Eq, V> {
    Parent,
    NextSibling,
    Child(u32),
    SetTo(C),
    Stop(V),
}

The direction in which a visitor wishes to go after visiting a node.

Variants

Parent

Visit the parent of the node which has been visited.

NextSibling

Visit the sibling of the node which has been visited.

Child(u32)

Visit the n-th child of the node which has been visited.

SetTo(C)

Visit a specific cursor.

Used when the traversable cannot figure out where to go on its own, for example if a visitor removes the node it was on.

Stop(V)

Stop the execution of the algorithm, producing a final value.
