Struct Color 

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

A straight (non-premultiplied) 8-bit-per-channel sRGB color.

Matches oxideav-core’s Rgba model; Color::to_oxideav is a zero-cost bridge used when building a scene.

Fields

r: u8

g: u8

b: u8

a: u8

Implementations

impl Color

pub const TRANSPARENT: Self

pub const BLACK: Self

pub const WHITE: Self

pub const fn rgb(r: u8, g: u8, b: u8) -> Self

pub const fn rgba(r: u8, g: u8, b: u8, a: u8) -> Self

pub fn from_hex(s: &str) -> Option<Self>

Parse #RGB, #RGBA, #RRGGBB, or #RRGGBBAA (leading # optional). Returns None on any malformed input.

pub const fn with_alpha(self, a: u8) -> Self

Returns a copy with the alpha channel replaced.

pub fn mix(self, other: Color, t: f64) -> Color

Linear blend toward other by t (0.0 = self, 1.0 = other), per channel including alpha. t is clamped to [0, 1].

pub fn lighten(self, amount: f64) -> Color

Blend amount (0..=1) toward white — for hover/active tints.

pub fn darken(self, amount: f64) -> Color

Blend amount (0..=1) toward black.

pub fn luminance(self) -> f64

Perceptual luminance in [0, 1] (ITU-R BT.709 weights), for picking a readable on-color.

pub fn on_color(self) -> Color

Black or white, whichever contrasts better with self.

pub const fn to_oxideav(self) -> Rgba

Bridge to the oxideav-core color used by the scene graph.

Trait Implementations

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 Copy for Color

impl Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl Eq for Color

impl From<Color> for Rgba

fn from(c: Color) -> Rgba

Converts to this type from the input type.

impl Hash for Color

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
