#[repr(C)]pub struct CpuSet { /* fields omitted */ }

[−] Expand description

CpuSet represent a bit-mask of CPUs. CpuSets are used by sched_setaffinity and sched_getaffinity for example.

This is a wrapper around libc::cpu_set_t.

Implementations

impl CpuSet[−]

pub fn new() -> CpuSet[−]

Create a new and empty CpuSet.

pub fn is_set(&self, field: usize) -> Result<bool>[−]

Test to see if a CPU is in the CpuSet. field is the CPU id to test

pub fn set(&mut self, field: usize) -> Result<()>[−]

Add a CPU to CpuSet. field is the CPU id to add

pub fn unset(&mut self, field: usize) -> Result<()>[−]

Remove a CPU from CpuSet. field is the CPU id to remove

pub fn count() -> usize[−]

Return the maximum number of CPU in CpuSet
