Struct Cpu

Source 
pub struct Cpu { /* private fields */ }
Expand description

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§

Source§

impl Cpu

Source

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());
}
Source

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());
}
