Struct Color 

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

An RGBA color with f32 components in the 0.0..=1.0 range.

Colors are stored in linear RGBA order and can be constructed from floats, u8 values, or hex codes:

use astrelis_render::Color;

let red = Color::rgb(1.0, 0.0, 0.0);
let semi_transparent = Color::rgba(1.0, 1.0, 1.0, 0.5);
let from_hex = Color::from_hex(0xFF8800);
let from_bytes = Color::from_rgba_u8(128, 64, 32, 255);

The struct is #[repr(C)] and implements bytemuck::Pod, so it can be used directly in GPU uniform/vertex buffers.

Implementations

impl Color

pub const WHITE: Color

pub const CYAN: Color

pub const MAGENTA: Color

pub const TRANSPARENT: Color

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

Create a color from RGB components with full opacity (alpha = 1.0).

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

Create a color from RGBA components.

pub fn from_rgba_u8(r: u8, g: u8, b: u8, a: u8) -> Color

Create a color from 8-bit RGBA values (0–255 mapped to 0.0–1.0).

pub fn from_rgb_u8(r: u8, g: u8, b: u8) -> Color

Create a color from 8-bit RGB values with full opacity.

pub fn from_hex(hex: u32) -> Color

Create a color from a 24-bit RGB hex value (e.g. 0xFF8800).

pub fn from_hex_alpha(hex: u32) -> Color

Create a color from a 32-bit RGBA hex value (e.g. 0xFF880080).

pub fn to_wgpu(self) -> Color

Convert to the equivalent wgpu::Color (f64 components).

pub fn to_array(self) -> [f32; 4]

Convert to an [r, g, b, a] array.

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<(), Error>

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl From<[f32; 3]> for Color

fn from(arr: [f32; 3]) -> Color

Converts to this type from the input type.

impl From<[f32; 4]> for Color

fn from(arr: [f32; 4]) -> Color

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 Zeroable for Color

fn zeroed() -> Self

Calls zeroed.

impl Copy for Color

impl Pod for Color

impl StructuralPartialEq for Color
