Struct Color 

#[repr(C)]
pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

RGBA color with linear f32 channels in [0.0, 1.0].

Layout is repr(C) and Pod/Zeroable so the type can be uploaded directly into GPU buffers. Channels are not premultiplied unless Color::premultiplied has been called explicitly.

Fields

r: f32

Red channel.

g: f32

Green channel.

b: f32

Blue channel.

a: f32

Alpha channel.

Implementations

impl Color

pub const TRANSPARENT: Self

Fully transparent.

pub const BLACK: Self

Opaque black.

pub const WHITE: Self

Opaque white.

pub const RED: Self

Opaque pure red.

pub const GREEN: Self

Opaque pure green.

pub const BLUE: Self

Opaque pure blue.

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

Construct an opaque color from f32 RGB channels.

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

Construct a color from f32 RGBA channels.

pub fn rgb_u8(r: u8, g: u8, b: u8) -> Self

Construct an opaque color from u8 RGB channels (0–255).

pub fn rgba_u8(r: u8, g: u8, b: u8, a: u8) -> Self

Construct a color from u8 RGBA channels (0–255).

pub const fn with_alpha(self, a: f32) -> Self

Return a copy with the alpha channel replaced.

pub fn premultiplied(self) -> Self

Return a copy with RGB premultiplied by alpha.

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 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 Zeroable for Color

fn zeroed() -> Self

Calls zeroed.

impl Copy for Color

impl Pod for Color

impl StructuralPartialEq for Color
