Struct LightValueRange 

pub struct LightValueRange { /* private fields */ }

A validated light value range advertised by a device driver.

Implementations

impl LightValueRange

pub const fn new( min: u16, max: u16, step: u16, unit: LightValueUnit, ) -> Result<Self, LightValueRangeError>

Construct a range after validating its bounds and quantization grid.

The upper bound must lie on the same grid as the lower bound. This keeps driver quantization total: a valid range can never produce a value outside the advertised interval or between device-supported stops.

pub const fn min(self) -> u16

Inclusive lower bound in the advertised unit.

pub const fn max(self) -> u16

Inclusive upper bound in the advertised unit.

pub const fn step(self) -> u16

Supported increment.

pub const fn unit(self) -> LightValueUnit

Unit represented by this range.

pub fn contains(self, value: u16) -> bool

Whether value is representable without clamping or quantization.

pub fn quantize(self, value: u16) -> u16

Snap value to the nearest supported point inside this range.

pub fn native_for_percent(self, percent: u8) -> Option<u16>

Map normalized brightness to the nearest native value in this range.

pub fn percent_for_native(self, value: u16) -> Option<u8>

Convert a supported native value to normalized brightness.
