Struct Color 

pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

RGBA color, each channel in [0, 1].

Fields

r: f32

Red channel.

g: f32

Green channel.

b: f32

Blue channel.

a: f32

Alpha channel.

Implementations

impl Color

pub const fn rgb(r: f32, g: f32, b: f32) -> Self

Constructs a fully-opaque Color from r, g, b channels.

pub const fn rgba(r: f32, g: f32, b: f32, a: f32) -> Self

Constructs a Color from r, g, b, a channels.

pub fn to_rgba8(self) -> [u8; 4]

Packs into [R, G, B, A] bytes, clamping each channel to [0, 1] and rounding to u8.

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() -> Color

Returns the “default value” for a type.

impl From<&'static str> for Color

fn from(hex: &'static str) -> Self

Parses #rgb, #rgba, #rrggbb, or #rrggbbaa literals. Falls back to Color::default on any parse error - this impl is intended for the Adwaita defaults table where every literal is known-good at compile time.

impl From<(u8, u8, u8)> for Color

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

Converts to this type from the input type.

impl From<(u8, u8, u8, u8)> for Color

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

Converts to this type from the input type.

impl From<Color> for PropertyValue

fn from(v: Color) -> Self

Converts to this type from the input type.

impl From<PropertyValue> for Color

fn from(v: PropertyValue) -> 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
