Implementations

impl BacklitDevice[src]

pub fn default(root_scaling: f64) -> Result<Self, Error>[src]

Use the default backlit device, i.e. the first one found in the /sys/class/backlight directory.

pub fn from_device(device: String, root_scaling: f64) -> Result<Self, Error>[src]

Use the backlit device device. Returns an error if a directory for that device is not found.

pub fn brightness(&self) -> Result<u64, Error>[src]

Query the brightness value for this backlit device, as a percent.

pub fn set_brightness(&self, value: u64) -> Result<(), Error>[src]

Set the brightness value for this backlit device, as a percent.

fn set_brightness_via_dbus(&self, raw_value: u64) -> Result<(), Error>[src]

pub fn brightness_file(&self) -> PathBuf[src]

The brightness file itself.
