Struct Color 

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

RGBA color (components 0.0–1.0).

Converts to CGColor automatically via Into.

Fields

r: f64

Red component (0.0 to 1.0).

g: f64

Green component (0.0 to 1.0).

b: f64

Blue component (0.0 to 1.0).

a: f64

Alpha component (0.0 = transparent, 1.0 = opaque).

Implementations

impl Color

Transparent (fully transparent black).

pub const BLACK: Self

Black.

pub const WHITE: Self

White.

pub const RED: Self

pub const DARK_GRAY: Self

Dark gray (25% intensity).

pub const GRAY: Self

Gray (50% intensity).

pub const LIGHT_GRAY: Self

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

Create a new color from RGBA components (0.0 to 1.0).

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

Create a new opaque color from RGB components (0.0 to 1.0).

pub fn rgba8(r: u8, g: u8, b: u8, a: u8) -> Self

Create a color from 8-bit RGBA components (0 to 255).

pub fn rgb8(r: u8, g: u8, b: u8) -> Self

Create an opaque color from 8-bit RGB components (0 to 255).

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

Create a color from a hex string (e.g., “#FF0000” or “FF0000”).

Supports 6-character (RGB) and 8-character (RGBA) hex strings.

pub const fn gray(intensity: f64) -> Self

Create a grayscale color with the given intensity (0.0 to 1.0).

pub const fn gray_alpha(intensity: f64, alpha: f64) -> Self

Create a grayscale color with alpha.

pub const fn with_alpha(self, alpha: f64) -> Self

Return a new color with the specified alpha component.

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 Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Self

Returns the “default value” for a type.

impl From<&Color> for CFRetained<CGColor>

fn from(c: &Color) -> Self

Converts to this type from the input type.

impl From<Color> for CFRetained<CGColor>

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
