Getting a component temperature information.

Required Methods

fn temperature(&self) -> f32

Returns the temperature of the component (in celsius degree).

use sysinfo::{ComponentExt, System, SystemExt};

let s = System::new_all();
for component in s.components() {
    println!("{}°C", component.temperature());
}

Linux

Returns f32::NAN if it failed to retrieve it.

fn max(&self) -> f32

Returns the maximum temperature of the component (in celsius degree).

Note: if temperature is higher than the current max, max value will be updated on refresh.

use sysinfo::{ComponentExt, System, SystemExt};

let s = System::new_all();
for component in s.components() {
    println!("{}°C", component.max());
}

Linux

May be computed by sysinfo from kernel. Returns f32::NAN if it failed to retrieve it.

fn critical(&self) -> Option<f32>

Returns the highest temperature before the component halts (in celsius degree).

use sysinfo::{ComponentExt, System, SystemExt};

let s = System::new_all();
for component in s.components() {
    println!("{:?}°C", component.critical());
}

Linux

Critical threshold defined by chip or kernel.

fn label(&self) -> &str

Returns the label of the component.

use sysinfo::{ComponentExt, System, SystemExt};

let s = System::new_all();
for component in s.components() {
    println!("{}", component.label());
}

Linux

Since components informations are retrieved thanks to hwmon, the labels are generated as follows. Note: it may change and it was inspired by sensors own formatting.

name	label	device_model	id_sensor	Computed label by sysinfo
✓	✓	✓	✓	"{name} {label} {device_model} temp{id}"
✓	✓	✗	✓	"{name} {label} {id}"
✓	✗	✓	✓	"{name} {device_model}"
✓	✗	✗	✓	"{name} temp{id}"

fn refresh(&mut self)

Refreshes component.

use sysinfo::{ComponentExt, System, SystemExt};

let mut s = System::new_all();
for component in s.components_mut() {
    component.refresh();
}
