#[repr(transparent)]
pub struct PremultipliedColorU8(_);

A 32-bit premultiplied RGBA color value.

Byteorder: ABGR

Implementations

impl PremultipliedColorU8

pub const TRANSPARENT: Self = _

A transparent color.

pub fn from_rgba(r: u8, g: u8, b: u8, a: u8) -> Option<Self>

Creates a new premultiplied color.

RGB components must be <= alpha.

pub const fn red(self) -> u8

Returns color’s red component.

The value is <= alpha.

pub const fn green(self) -> u8

Returns color’s green component.

The value is <= alpha.

pub const fn blue(self) -> u8

Returns color’s blue component.

The value is <= alpha.

pub const fn alpha(self) -> u8

Returns color’s alpha component.

pub fn is_opaque(&self) -> bool

Check that color is opaque.

Alpha == 255

pub const fn get(self) -> u32

Returns the value as a primitive type.

pub fn demultiply(&self) -> ColorU8

Returns a demultiplied color.

Trait Implementations

impl Clone for PremultipliedColorU8

fn clone(&self) -> PremultipliedColorU8

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PremultipliedColorU8

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

Formats the value using the given formatter.

impl PartialEq<PremultipliedColorU8> for PremultipliedColorU8

fn eq(&self, other: &PremultipliedColorU8) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for PremultipliedColorU8

fn zeroed() -> Self

Calls zeroed.
