Trait Implementations

impl<'a, T: 'a> Clone for NodeRef<'a, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<'a, T: 'a> From<NodeMut<'a, T>> for NodeRef<'a, T>

fn from(node: NodeMut<'a, T>) -> Self

Converts to this type from the input type.

impl<'a, T: 'a> PartialEq for NodeRef<'a, T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
