Struct Oklab 

pub struct Oklab<const OFFSET: usize = 0>;

Oklab perceptual color space by Björn Ottosson, 2020.

Better hue linearity than CIELab. L is lightness [0, 1], a and b are opponent axes. D65 adaptation is baked into the specification. Adopted in CSS Color Level 4.

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<const OFFSET: usize> ChannelMap<4> for Oklab<OFFSET>

const INDICES: [usize; 4]

BackingStore positions of all N channels in logical order.

impl<const OFFSET: usize> Clone for Oklab<OFFSET>

fn clone(&self) -> Oklab<OFFSET>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const OFFSET: usize> Debug for Oklab<OFFSET>

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

Formats the value using the given formatter.

impl<const OFFSET: usize> Default for Oklab<OFFSET>

fn default() -> Oklab<OFFSET>

Returns the “default value” for a type.

impl<const OFFSET: usize> PartialEq for Oklab<OFFSET>

fn eq(&self, other: &Oklab<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.
