Struct loom::sync::atomic::AtomicUsize

pub struct AtomicUsize(_);

Mock implementation of std::sync::atomic::AtomicUsize.

Implementations

impl AtomicUsize

pub fn new(v: usize) -> AtomicUsize

Creates a new instance of AtomicUsize.

pub fn get_mut(&mut self) -> &mut usize

Returns a mutable reference to the underlying integer.

Panics

This function panics if the access is invalid under the Rust memory model.

pub fn load(&self, order: Ordering) -> usize

Loads a value from the atomic integer.

pub fn store(&self, val: usize, order: Ordering)

Stores a value into the atomic integer.

pub fn swap(&self, val: usize, order: Ordering) -> usize

Stores a value into the atomic integer, returning the previous value.

pub fn compare_and_swap(
    &self,
    current: usize,
    new: usize,
    order: Ordering
) -> usize

Stores a value into the atomic integer if the current value is the same as the current value.

pub fn compare_exchange(
    &self,
    current: usize,
    new: usize,
    success: Ordering,
    failure: Ordering
) -> Result<usize, usize>

Stores a value into the atomic integer if the current value is the same as the current value.

pub fn fetch_add(&self, val: usize, order: Ordering) -> usize

Adds to the current value, returning the previous value.

pub fn fetch_sub(&self, val: usize, order: Ordering) -> usize

Subtracts from the current value, returning the previous value.

pub fn fetch_and(&self, val: usize, order: Ordering) -> usize

Bitwise “and” with the current value.

pub fn fetch_or(&self, val: usize, order: Ordering) -> usize

Bitwise “or” with the current value.
