Struct CpuSet

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

CpuSet represents a bit-mask of CPUs.

CpuSets are used by sched_setaffinity and sched_getaffinity, for example.

Implementations

impl CpuSet

pub const MAX_CPU: usize = 1_024usize

The maximum number of CPU in CpuSet.

pub fn new() -> Self

Create a new and empty CpuSet.

pub fn is_set(&self, field: usize) -> 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)

Add a CPU to CpuSet.

field is the CPU id to add.

pub fn unset(&mut self, field: usize)

Remove a CPU from CpuSet.

field is the CPU id to remove.

pub fn count(&self) -> u32

Count the number of CPUs set in the CpuSet.

pub fn clear(&mut self)

Zeroes the CpuSet.

Trait Implementations

impl Clone for CpuSet

fn clone(&self) -> CpuSet

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CpuSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CpuSet

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CpuSet

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CpuSet

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
