Struct orx_selfref_col::NodeRefSingle

pub struct NodeRefSingle<'a, V, T>(/* private fields */)
where
    V: Variant<'a, T>;

A single node reference.

Underlying reference storage is an optional reference to the single referenced node.

The following are some example references which can be expressed by NodeRefSingle:

• previous or next node in a linked list;
• parent of a node in a tree.

Trait Implementations

impl<'a, V, T> Clone for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

fn clone(&self) -> Self

Clones the reference.

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

Performs copy-assignment from source.

impl<'a, T: Debug, V> Debug for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

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

Formats the value using the given formatter.

impl<'a, V, T> Default for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

fn default() -> Self

Creates an empty reference.

impl<'a, V, T> From<&'a Node<'a, V, T>> for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

fn from(single_reference: &'a Node<'a, V, T>) -> Self

Converts to this type from the input type.

impl<'a, V, T> From<Option<&'a Node<'a, V, T>>> for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

fn from(value: Option<&'a Node<'a, V, T>>) -> Self

Converts to this type from the input type.

impl<'a, V, T> NodeRefs<'a, V, T> for NodeRefSingle<'a, V, T>

where V: Variant<'a, T>,

type References = Option<&'a Node<'a, V, T>>

Type of the underlying references.

fn new(references: Self::References) -> Self

Creates a new node references for the given references.

fn get(&self) -> &Self::References

Returns a reference to the underlying references.

fn get_mut(&mut self) -> &mut Self::References

Returns a mutable reference to the underlying references.

fn update_reference( &mut self, prior_reference: &'a Node<'a, V, T>, new_reference: &'a Node<'a, V, T> )

Updates this reference so that all internal references to the prior_reference are updated as new_reference. Does nothing if this NodeRefs does not hold a reference to the prior_reference.

fn referenced_nodes(&self) -> impl Iterator<Item = &'a Node<'a, V, T>>

where V: 'a, T: 'a,

Returns an iterator to the referenced nodes.

fn empty() -> Self

Creates empty references.
