Struct Component 

pub struct Component { /* private fields */ }

Getting a component temperature information.

use sysinfo::Components;

let components = Components::new_with_refreshed_list();
for component in &components {
    if let Some(temperature) = component.temperature() {
        println!("{} {temperature}°C", component.label());
    } else {
        println!("{} (unknown temperature)", component.label());
    }
}

Implementations

impl Component

pub fn temperature(&self) -> Option<f32>

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

Linux

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

use sysinfo::Components;

let components = Components::new_with_refreshed_list();
for component in &components {
    if let Some(temperature) = component.temperature() {
        println!("{temperature}°C");
    }
}

pub fn max(&self) -> Option<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.

Linux

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

use sysinfo::Components;

let components = Components::new_with_refreshed_list();
for component in &components {
    if let Some(max) = component.max() {
        println!("{max}°C");
    }
}

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

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

Linux

Critical threshold defined by chip or kernel.

use sysinfo::Components;

let components = Components::new_with_refreshed_list();
for component in &components {
    if let Some(critical) = component.critical() {
        println!("{critical}°C");
    }
}

pub fn label(&self) -> &str

Returns the label of the component.

Linux

Since components information is 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}"
✓	✓	✗	✓	"{name} {label}"
✓	✗	✓	✓	"{name} {device_model}"
✓	✗	✗	✓	"{name} temp{id}"

use sysinfo::Components;

let components = Components::new_with_refreshed_list();
for component in &components {
    println!("{}", component.label());
}

pub fn refresh(&mut self)

Refreshes component.

use sysinfo::Components;

let mut components = Components::new_with_refreshed_list();
for component in components.iter_mut() {
    component.refresh();
}

Trait Implementations

impl Debug for Component

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.
