Struct vergen::CpuRefreshKind

source ·

pub struct CpuRefreshKind { /* private fields */ }

Available on crate feature si only.

Expand description

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::{CpuRefreshKind, System};

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§

source §

impl CpuRefreshKind

source

pub fn new() -> CpuRefreshKind

Creates a new CpuRefreshKind with every refresh set to false.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::new();

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

source

pub fn everything() -> CpuRefreshKind

Creates a new CpuRefreshKind with every refresh set to true.

use sysinfo::CpuRefreshKind;

let r = CpuRefreshKind::everything();

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

source

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);

source

pub fn with_cpu_usage(self) -> CpuRefreshKind

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);

source

pub fn without_cpu_usage(self) -> CpuRefreshKind

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);

source

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);

source

pub fn with_frequency(self) -> CpuRefreshKind

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);

source

pub fn without_frequency(self) -> CpuRefreshKind

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);
