Struct sysinfo::CpuRefreshKind

pub struct CpuRefreshKind { /* private fields */ }

Used to determine what you want to refresh specifically on the Cpu type.

⚠️ Just like all other refresh types, ruling out a refresh doesn’t assure you that the information won’t be retrieved if the information is accessible without needing extra computation.

use sysinfo::{CpuExt, CpuRefreshKind, System, SystemExt};

let mut system = System::new();

// We don't want to update all the CPU information.
system.refresh_cpu_specifics(CpuRefreshKind::everything().without_frequency());

for cpu in system.cpus() {
    assert_eq!(cpu.frequency(), 0);
}

Implementations

impl CpuRefreshKind

pub fn new() -> Self

Creates a new CpuRefreshKind with every refresh set to false.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();

assert_eq!(r.frequency(), false);

pub fn everything() -> Self

Creates a new CpuRefreshKind with every refresh set to true.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::everything();

assert_eq!(r.frequency(), true);

pub fn cpu_usage(&self) -> bool

Returns the value of the “cpu_usage” refresh kind.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();
assert_eq!(r.cpu_usage(), false);

let r = r.with_cpu_usage();
assert_eq!(r.cpu_usage(), true);

let r = r.without_cpu_usage();
assert_eq!(r.cpu_usage(), false);

pub fn with_cpu_usage(self) -> Self

Sets the value of the “cpu_usage” refresh kind to true.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();
assert_eq!(r.cpu_usage(), false);

let r = r.with_cpu_usage();
assert_eq!(r.cpu_usage(), true);

pub fn without_cpu_usage(self) -> Self

Sets the value of the “cpu_usage” refresh kind to false.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::everything();
assert_eq!(r.cpu_usage(), true);

let r = r.without_cpu_usage();
assert_eq!(r.cpu_usage(), false);

pub fn frequency(&self) -> bool

Returns the value of the “frequency” refresh kind.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();
assert_eq!(r.frequency(), false);

let r = r.with_frequency();
assert_eq!(r.frequency(), true);

let r = r.without_frequency();
assert_eq!(r.frequency(), false);

pub fn with_frequency(self) -> Self

Sets the value of the “frequency” refresh kind to true.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();
assert_eq!(r.frequency(), false);

let r = r.with_frequency();
assert_eq!(r.frequency(), true);

pub fn without_frequency(self) -> Self

Sets the value of the “frequency” refresh kind to false.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::everything();
assert_eq!(r.frequency(), true);

let r = r.without_frequency();
assert_eq!(r.frequency(), false);

Trait Implementations

impl Clone for CpuRefreshKind

fn clone(&self) -> CpuRefreshKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CpuRefreshKind

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

Formats the value using the given formatter.

impl Default for CpuRefreshKind

fn default() -> CpuRefreshKind

Returns the “default value” for a type.

impl PartialEq for CpuRefreshKind

fn eq(&self, other: &CpuRefreshKind) -> 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.
