Struct AtomicCpuSet Copy item path

impl AtomicCpuSet

pub fn new(value: CpuSet) -> Self

Creates a new AtomicCpuSet with an initial value.

pub fn load(&self, ordering: Ordering) -> CpuSet

Loads the value of the set with the given ordering.

This operation is not atomic. When racing with a Self::store operation, this load may return a set that contains a portion of the new value and a portion of the old value. Load on each specific word is atomic, and follows the specified ordering.

Note that load with [Ordering::Release] is a valid operation, which is different from the normal atomic operations. When coupled with [Ordering::Release], it actually performs fetch_or(0, Release).

pub fn store(&self, value: &CpuSet, ordering: Ordering)

Stores a new value to the set with the given ordering.

This operation is not atomic. When racing with a Self::load operation, that load may return a set that contains a portion of the new value and a portion of the old value. Load on each specific word is atomic, and follows the specified ordering.

pub fn add(&self, cpu_id: CpuId, ordering: Ordering)

Atomically adds a CPU with the given ordering.

pub fn remove(&self, cpu_id: CpuId, ordering: Ordering)

Atomically removes a CPU with the given ordering.

pub fn contains(&self, cpu_id: CpuId, ordering: Ordering) -> bool

Atomically checks if the set contains the specified CPU.
