Enum trees::linked::singly::walk::Visit

pub enum Visit<'a, T: 'a> {
    Begin(&'a Node<T>),
    End(&'a Node<T>),
    Leaf(&'a Node<T>),
}

Distinguish between visiting a leaf node and (begin/end of) visiting a branched node.

Variants

Begin(&'a Node<T>)

End(&'a Node<T>)

Leaf(&'a Node<T>)

Implementations

impl<'a, T: 'a> Visit<'a, T>

pub fn node(&self) -> &Node<T>

Returns the node under visit, regardless of whether it is a leaf node or (begin/end of) visiting a branched node.

Trait Implementations

impl<'a, T: Clone + 'a> Clone for Visit<'a, T>

fn clone(&self) -> Visit<'a, T>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, T: Copy + 'a> Copy for Visit<'a, T>

impl<'a, T: Debug + 'a> Debug for Visit<'a, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: Eq + 'a> Eq for Visit<'a, T>

impl<'a, T: PartialEq + 'a> PartialEq<Visit<'a, T>> for Visit<'a, T>

fn eq(&self, other: &Visit<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Visit<'a, T>) -> bool

This method tests for !=.
