Struct Color 

pub struct Color {
    pub r: f64,
    pub g: f64,
    pub b: f64,
    pub a: f64,
}

sRGB color, 0.0–1.0 components. Semantic theme tokens (§6.3) resolve to these in the backend.

Fields

r: f64

g: f64

b: f64

a: f64

Implementations

impl Color

pub const BLACK: Color

pub const WHITE: Color

pub const CLEAR: Color

pub const fn rgba(r: f64, g: f64, b: f64, a: f64) -> Color

pub const fn rgb(r: f64, g: f64, b: f64) -> Color

pub const fn hex(v: u32) -> Color

0xRRGGBB

pub fn hsl(h: f64, s: f64, l: f64) -> Color

From HSL — h in degrees (wraps mod 360), s/l in 0.0..=1.0. Color is the one color type every parameter accepts, so this makes HSL usable everywhere a color is.

pub fn hsla(h: f64, s: f64, l: f64, a: f64) -> Color

pub fn hsv(h: f64, s: f64, v: f64) -> Color

From HSV/HSB — h degrees (wraps), s/v in 0.0..=1.0.

pub fn hsva(h: f64, s: f64, v: f64, a: f64) -> Color

pub fn to_hsl(&self) -> (f64, f64, f64)

Decompose to (hue°, saturation, lightness) (HSL). Hue is 0.0 for greys.

pub fn lerp_hsl(self, to: Color, t: f64) -> Color

Interpolate toward to in HSL space, taking the shortest hue arc (t in 0.0..=1.0). A hue-space blend (red→green sweeps through yellow) rather than the muddy RGB straight line — used by the canvas / self-driven animation path (native widget color animation interpolates in the toolkit’s own space).

Trait Implementations

impl Animatable for Color

fn lerp(self, to: Color, t: f64) -> Color

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl From<Color> for Paint

fn from(c: Color) -> Self

Converts to this type from the input type.

impl PartialEq for Color

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

impl Copy for Color

impl StructuralPartialEq for Color
