Struct Rgba8

#[repr(C)]
pub struct Rgba8 {
    pub r: u8,
    pub g: u8,
    pub b: u8,
    pub a: u8,
}

A packed representation of sRGB colors.

Encoding sRGB with 8 bits per component is extremely common, as it is efficient and convenient, even if limited in accuracy and gamut.

This is not meant to be a general purpose color type and is intended for use with AlphaColor::to_rgba8 and OpaqueColor::to_rgba8.

For a pre-multiplied packed representation, see PremulRgba8.

Fields

r: u8

Red component.

g: u8

Green component.

b: u8

Blue component.

a: u8

Alpha component.

Alpha is interpreted as separated alpha.

Implementations

impl Rgba8

pub const fn to_u8_array(self) -> [u8; 4]

Returns the color as a [u8; 4].

The color values will be in the order [r, g, b, a].

pub const fn from_u8_array([r, g, b, a]: [u8; 4]) -> Self

Convert the [u8; 4] byte array into an Rgba8 color.

The color values must be given in the order [r, g, b, a].

pub const fn to_u32(self) -> u32

Returns the color as a little-endian packed value, with r the least significant byte and a the most significant.

pub const fn from_u32(packed_bytes: u32) -> Self

Interpret the little-endian packed value as a color, with r the least significant byte and a the most significant.

Trait Implementations

impl Clone for Rgba8

fn clone(&self) -> Rgba8

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rgba8

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

Formats the value using the given formatter.

impl Display for Rgba8

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

Formats the value using the given formatter.

impl From<Rgba8> for AlphaColor<Srgb>

fn from(value: Rgba8) -> Self

Converts to this type from the input type.

impl LowerHex for Rgba8

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

Formats the value using the given formatter.

impl PartialEq for Rgba8

fn eq(&self, other: &Rgba8) -> 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 UpperHex for Rgba8

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

Formats the value using the given formatter.
