Struct Lab 

pub struct Lab<W: Illuminant = D65, const OFFSET: usize = 0>(/* private fields */);

CIE 1976 Lab* color space under reference white W.

Perceptually uniform for small color differences. L* is lightness [0, 100], a* is green-red [-128, 127], b* is blue-yellow [-128, 127]. Reference: CIE 015:2018.

OFFSET is the storage index of the first color channel. 0 (default) places color channels at [0, 1, 2] with alpha at 3. 1 places color channels at [1, 2, 3] with alpha at 0, matching alpha-first texture layouts.

Trait Implementations

impl<W: Illuminant, const OFFSET: usize> ChannelMap<4> for Lab<W, OFFSET>

const INDICES: [usize; 4]

BackingStore positions of all N channels in logical order.

impl<W: Clone + Illuminant, const OFFSET: usize> Clone for Lab<W, OFFSET>

fn clone(&self) -> Lab<W, OFFSET>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<W: Debug + Illuminant, const OFFSET: usize> Debug for Lab<W, OFFSET>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<W: Default + Illuminant, const OFFSET: usize> Default for Lab<W, OFFSET>

fn default() -> Lab<W, OFFSET>

Returns the “default value” for a type.

impl<W: PartialEq + Illuminant, const OFFSET: usize> PartialEq for Lab<W, OFFSET>

fn eq(&self, other: &Lab<W, OFFSET>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
