Struct AtomicCell 

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

Thread-safe atomic cell wrapper

Implementations

impl<T> AtomicCell<T>

pub fn new(val: T) -> Self

Create a new atomic cell containing val

pub fn get(&self) -> WatchGuardRef<'_, T>

Shared (read-only) access via sync

pub fn with<R>(&self, f: impl FnOnce(&T) -> R) -> R

Executes a closure while holding a shared guard.

pub fn get_mut(&self) -> WatchGuardMut<'_, T>

Exclusive mutable access via sync

pub fn with_mut<R>(&self, f: impl FnOnce(&mut T) -> R) -> R

Executes a closure while holding an exclusive guard.

pub fn as_ptr(&self) -> *mut T

Returns a raw pointer to the inner value

pub fn into_inner(self) -> T

Consumes the AtomicCell and returns the inner value.

Panics

Panics if there are other clones of this AtomicCell still alive.

pub fn update<F>(&self, f: F)

where F: FnMut(&mut T),

Atomic update with exclusive closure

pub fn swap(&self, val: T) -> T

Swap the value, returning the old one

pub fn store(&self, val: T)

Store a new value, dropping the old one

impl<T: Copy + Eq> AtomicCell<T>

pub fn compare_exchange( &self, current: T, new: T, ) -> Result<T, WatchGuardMut<'_, T>>

Compare-and-swap: if current == stored, write new and return Ok(old). Otherwise return Err with the guard still held.
