Struct omnisensor::sysfs::SysfsSensorIO

pub struct SysfsSensorIO {
    fd: File,
    scale: f64,
}

Information for reading sensor data from sysfs.

Fields

fd: File

A file descriptor to (asynchronously) read from.

scale: f64

A multiplicative scale factor to convert raw sysfs file data to the desired units.

For example, the hwmon subsystem provides temperature readings in millidegrees C, so 0.001 here would convert that to degrees C as desired elsewhere.

Implementations

impl SysfsSensorIO

pub async fn new(file: &HwmonFileInfo) -> Result<Self, Box<dyn Error>>

Construct a SysfsSensorIO for a provided hwmon file.

For use with SensorIO::Sysfs.

pub async fn read(&mut self) -> Result<f64, Box<dyn Error>>

Read a sensor sample (in natural units, e.g. degrees C instead of hwmon’s millidegrees C).
