Struct Oklch 

pub struct Oklch {
    pub l: f32,
    pub c: f32,
    pub h: f32,
}

A colour in OKLCH: perceptual lightness l in [0, 1], chroma c (0 is grey; sRGB tops out near 0.37) and hue h in degrees.

The design language states every neutral and identity colour here, because equal l reads as equal lightness whatever the hue: a theme can rotate its temperature, or a palette its hues, without moving contrast.

Fields

l: f32

c: f32

h: f32

Implementations

impl Oklch

pub const fn new(l: f32, c: f32, h: f32) -> Oklch

pub fn to_color(self) -> AlphaColor<Srgb>

The opaque sRGB colour, gamut-mapped by lowering chroma: lightness and hue are kept exactly, and only as much chroma is given up as the sRGB cube demands (a light cyan cannot carry the chroma a light violet can).

pub fn from_color(color: AlphaColor<Srgb>) -> Oklch

The OKLCH coordinates of an sRGB colour (alpha ignored). A grey’s hue is meaningless and comes back as 0.

Trait Implementations

impl Clone for Oklch

fn clone(&self) -> Oklch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Oklch

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

Formats the value using the given formatter.

impl PartialEq for Oklch

fn eq(&self, other: &Oklch) -> 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.
