libmedium

A safe rust library to communicate with the sysfs interface of lm-sensors.

Usage

Just add this to your Cargo.toml file:

[dependencies]
libmedium = "0.8"

Cargo-Features

Standard features

• writeable: Standard feature that enables all functions that write to sysfs. This includes setting pwm values and disabling sensors.
• sync: Build synchronous versions of all sensors.

• virtual_sensors: Feature that lets you create virtual sensors. Virtual sensors don't belong to sysfs but can be any file provided by a driver or the user.

Non standard features

• uom_units: Sensor values are returned as types from the uom crate.
• unrestricted_parsing: This feature allows parsing of paths other than '/sys/class/hwmon'. This should only be useful for testing and debugging.
• async: Build asynchronous versions of all sensors.

Examples

• Print the temperature of all the temp sensors in your system:

use libmedium::{
    parse_hwmons,
    sensors::sync_sensors::{temp::TempSensor, Sensor},
};

let hwmons = parse_hwmons().unwrap();
for hwmon in &hwmons {
    println!("hwmon{} with name {}:", hwmon.index(), hwmon.name());
    for (_, temp_sensor) in hwmon.temps() {
        let temperature = temp_sensor.read_input().unwrap();
        println!("\t{}: {}", temp_sensor.name(), temperature);
    }
}

• Set the pwm value of all your pwm capable fans to full speed (this requires the writeable feature to not be disabled):

use libmedium::{
    parse_hwmons,
    sensors::sync_sensors::pwm::WriteablePwmSensor,
    units::{Pwm, PwmEnable},
};

let hwmons = parse_hwmons().unwrap();
for hwmon in &hwmons {
    for (_, pwm) in hwmon.writeable_pwms() {
        pwm.write_enable(PwmEnable::ManualControl).unwrap();
        pwm.write_pwm(Pwm::FULLSPEED).unwrap();
    }
}
