Struct Cpu 

pub struct Cpu { /* private fields */ }

Contains all the methods of the Cpu struct.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let mut s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);

// Wait a bit because CPU usage is based on diff.
std::thread::sleep(sysinfo::MINIMUM_CPU_UPDATE_INTERVAL);
// Refresh CPUs again to get actual value.
s.refresh_cpu_all();

for cpu in s.cpus() {
    println!("{}%", cpu.cpu_usage());
}

Implementations

impl Cpu

pub fn cpu_usage(&self) -> f32

Returns this CPU’s usage.

Note: You’ll need to refresh it at least twice (diff between the first and the second is how CPU usage is computed) at first if you want to have a non-zero value.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let mut s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);

// Wait a bit because CPU usage is based on diff.
std::thread::sleep(sysinfo::MINIMUM_CPU_UPDATE_INTERVAL);
// Refresh CPUs again to get actual value.
s.refresh_cpu_all();

for cpu in s.cpus() {
    println!("{}%", cpu.cpu_usage());
}

pub fn name(&self) -> &str

Returns this CPU’s name.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);
for cpu in s.cpus() {
    println!("{}", cpu.name());
}

pub fn vendor_id(&self) -> &str

Returns the CPU’s vendor id.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);
for cpu in s.cpus() {
    println!("{}", cpu.vendor_id());
}

pub fn brand(&self) -> &str

Returns the CPU’s brand.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);
for cpu in s.cpus() {
    println!("{}", cpu.brand());
}

pub fn frequency(&self) -> u64

Returns the CPU’s frequency.

use sysinfo::{System, RefreshKind, CpuRefreshKind};

let s = System::new_with_specifics(
    RefreshKind::nothing().with_cpu(CpuRefreshKind::everything()),
);
for cpu in s.cpus() {
    println!("{}", cpu.frequency());
}

Trait Implementations

impl Debug for Cpu

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
