Struct i3status_rs::blocks::backlight::BacklightConfig

pub struct BacklightConfig {
    pub device: Option<String>,
    pub step_width: u64,
    pub root_scaling: f64,
    pub invert_icons: bool,
}

Configuration for the Backlight block.

Fields

device: Option<String>

The backlight device in /sys/class/backlight/ to read brightness from.

step_width: u64

The steps brightness is in/decreased for the selected screen (When greater than 50 it gets limited to 50)

root_scaling: f64

Scaling exponent reciprocal (ie. root). Some devices expose raw values that are best handled with nonlinear scaling. The human perception of lightness is close to the cube root of relative luminance. Settings between 2.4 and 3.0 are worth trying. More information: https://en.wikipedia.org/wiki/Lightness

For devices with few discrete steps this should be 1.0 (linear).

invert_icons: bool
