Struct AtomicCell

pub struct AtomicCell<T: AtomicCellStorable> { /* private fields */ }

An atomic-based cell designed for holding Arc-style pointers.

Implementations

impl<T: AtomicCellStorable> AtomicCell<T>

pub fn new(value: T) -> Self

Create a new AtomicCell with the given initial value.

pub fn set(&self, value: T) -> T

Replace the value in the cell, returning the old value.

impl<T: AtomicCellStorable + Clone> AtomicCell<T>

pub fn get(&self) -> T

Returns a clone of the stored value.

impl<T: AtomicCellStorable + Default> AtomicCell<T>

pub fn take(&self) -> T

Take the value stored in the cell, replacing it with the default value.

impl<T> AtomicCell<Weak<T>>

pub fn empty() -> Self

Create a new AtomicCell with an empty Weak stored inside.

pub fn upgrade(&self) -> Option<Arc<T>>

Attempt to upgrade the Weak pointer to a strong Arc pointer.

pub fn store(&self, arc: &Arc<T>)

Downgrade the Arc value and store it in the cell.

impl<T> AtomicCell<Option<Weak<T>>>

pub fn upgrade(&self) -> Option<Arc<T>>

Attempt to upgrade the Weak pointer to a strong Arc pointer (if it is not None).

pub fn store(&self, arc: &Arc<T>)

Downgrade the Arc value and store it in the cell.
