Struct LightLevel

pub struct LightLevel(f32);

Expand description

The level of light intensity from 0-100.

Tuple Fields§

§0: f32

Implementations§

impl LightLevel

const ZERO: f32 = 0.0

pub fn abs(self) -> Self

Returns the absolute value of the light level.

pub fn off() -> Self

Returns a light level representing 0% output.

fn value(&self) -> f32

pub fn from_fraction(fraction: f32) -> Self

Given a value between 0.0 and 1, this normalizes LightLevel accordingly to 0-100.

pub fn as_fraction(&self) -> f32

Returns the level as a value between 0.0-1

pub fn as_10_base(&self) -> i16

Instead of 0-100, this returns a value between 0-10. Usefull for e.g. /sys/class/backlight/lm3630a_led/color that accepts a value between 0-10.

pub fn as_10_base_inverted(&self) -> i16

Similar to Self::as_10_base but instead of 10 being max, 0 is max.
