Struct CpuSet

pub struct CpuSet { /* private fields */ }

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 const fn count() -> usize

Return the maximum number of CPU in 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: &CpuSet) -> 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.
