pub struct AtomicU64 {
    value: UnsafeCell<u64>,
}

An atomic u64 implemented by disabling interrupts around each operation.

Fields

value: UnsafeCell<u64>

Implementations

impl AtomicU64

pub const fn new(value: u64) -> Self

Creates a new atomic u64.

pub fn load(&self, _: Ordering) -> u64

Loads the value.

pub fn store(&self, value: u64, _: Ordering)

Stores a value.

pub fn compare_exchange( &self, current: u64, new: u64, _: Ordering, _: Ordering, ) -> Result<u64, u64>

Compares the value and exchanges it.

pub fn fetch_add(&self, value: u64, _: Ordering) -> u64

Fetches and adds, returning the previous value.

pub fn fetch_update<F>( &self, _: Ordering, _: Ordering, f: F, ) -> Result<u64, u64>

where F: FnMut(u64) -> Option<u64>,

Fetches a value, applies the function and writes it back atomically.
