Trait Implementations

impl<N: Node> Clone for RootToken<N>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug + Node> Debug for RootToken<N>

where N::Base: Debug, N::Token: Debug,

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

Formats the value using the given formatter.

impl<N: Node> Hash for RootToken<N>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<N: Node> NodeToken<<N as Node>::Base> for RootToken<N>

fn parent( &self, arena: &Arena<N::Base> ) -> Option<<<N::Base as BaseNode>::Branch as Node>::Token>

Returns this node’s parent’s token.

fn ancestors<'arena>( &self, arena: &'arena Arena<N::Base> ) -> Ancestors<'arena, N::Base>

Returns an iterator over the tokens of this node’s ancestors.

impl<N: Node, I: Idx> PartialEq<I> for RootToken<N>

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

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

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

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