Struct Atomic 

pub struct Atomic<Inner>
where
    Inner: CubePrimitive,
{
    pub val: Inner,
}

An atomic numerical type wrapping a normal numeric primitive. Enables the use of atomic operations, while disabling normal operations. In WGSL, this is a separate type - on CUDA/SPIR-V it can theoretically be bitcast to a normal number, but this isn’t recommended.

Fields

val: Inner

Implementations

impl<Inner> Atomic<Inner>

where Inner: CubePrimitive, <Inner as CubePrimitive>::Scalar: Numeric,

pub fn load(&self) -> Inner

Load the value of the atomic.

pub fn store(&self, value: Inner)

Store the value of the atomic.

pub fn swap(&self, value: Inner) -> Inner

Atomically stores the value into the atomic and returns the old value.

pub fn fetch_add(&self, value: Inner) -> Inner

Atomically add a number to the atomic variable. Returns the old value.

pub fn fetch_sub(&self, value: Inner) -> Inner

Atomically subtracts a number from the atomic variable. Returns the old value.

pub fn fetch_max(&self, value: Inner) -> Inner

Atomically sets the value of the atomic variable to max(current_value, value). Returns the old value.

pub fn fetch_min(&self, value: Inner) -> Inner

Atomically sets the value of the atomic variable to min(current_value, value). Returns the old value.

impl<Inner> Atomic<Inner>

where Inner: CubePrimitive, <Inner as CubePrimitive>::Scalar: Int,

pub fn compare_exchange_weak(&self, cmp: Inner, value: Inner) -> Inner

Compare the value at pointer to cmp and set it to value only if they are the same. Returns the old value of the pointer before the store.

Tip

Compare the returned value to cmp to determine whether the store was successful.

pub fn fetch_and(&self, value: Inner) -> Inner

Executes an atomic bitwise and operation on the atomic variable. Returns the old value.

pub fn fetch_or(&self, value: Inner) -> Inner

Executes an atomic bitwise or operation on the atomic variable. Returns the old value.

Executes an atomic bitwise xor operation on the atomic variable. Returns the old value.
