Struct orx_selfref_col::NodeDataLazyClose

pub struct NodeDataLazyClose<T>(/* private fields */);

Node data storage with lazy closure. In other words, the value is stored as it is and closing of a node means setting it to None.

Implementations

impl<T> NodeDataLazyClose<T>

pub fn closed() -> Self

Creates a new closed node data.

pub fn is_active(&self) -> bool

Returns whether or not the node data is active.

pub fn is_closed(&self) -> bool

Returns whether or not the node data is closed.

pub fn close(&mut self) -> Option<T>

Closes the node storage and returns the internally stored value.

Trait Implementations

impl<T: Clone> Clone for NodeDataLazyClose<T>

fn clone(&self) -> NodeDataLazyClose<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Default for NodeDataLazyClose<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> From<T> for NodeDataLazyClose<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T> NodeData<T> for NodeDataLazyClose<T>

fn active(value: T) -> Self

Creates a new active node data with the given value.

fn get(&self) -> Option<&T>

Returns a reference to the stored value; returns None if the node is not active.

fn get_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to the stored value; returns None if the node is not active.

fn swap_data(&mut self, new_value: T) -> T

Updates the node data with the new_value and returns back the old value.
