Struct CpuSet 

pub struct CpuSet { /* private fields */ }

CPU affinity expressed against one crate::runtime::TaskSystem topology.

Implementations

impl CpuSet

pub fn all(cpu_count: usize) -> Self

Creates a set that permits every CPU in a topology.

pub fn empty(cpu_count: usize) -> Self

Creates an empty CPU set for a topology.

pub fn insert(&mut self, cpu: CpuId) -> bool

Enables one CPU if it is represented by this set.

pub fn remove(&mut self, cpu: CpuId) -> bool

Disables one CPU if it is represented by this set.

pub fn contains(&self, cpu: CpuId) -> bool

Tests whether a CPU is allowed.

pub fn topology_len(&self) -> usize

Returns the number of CPUs represented by the set.

pub fn iter(&self) -> impl Iterator<Item = CpuId> + '_

Iterates selected CPUs in ascending logical-ID order.

pub fn covers(&self, required: &Self) -> bool

Returns whether this set permits every CPU selected by required.
