Struct arc_atomic::AtomicArc

pub struct AtomicArc<T> { /* private fields */ }

An atomic pointer to an Arc.

This pointer provides a safe atomic pointer to an Arc. Each load will clone the Arc ensuring that concurrent reads/writes will only drop the value when all references are decremented. The inner Arc can be swapped atomically with another value.

This value is not itself cloneable and can itself be wrapped in an Arc.

Implementations

impl<T> AtomicArc<T>

pub fn new(arc: Arc<T>) -> Self

Creates a new atomic pointer to an Arc.

pub fn load(&self) -> Arc<T>

Load the current value cloning the inner Arc.

This will increment a reference count of the current Arc and return this to the caller.

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

Replace the current value, dropping the previously stored Arc.

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

Swap the current value, returning the previously stored Arc.

The returned Arc may have additional references still held by other load calls previously requested.
