Enum PixelOrder 

pub enum PixelOrder {
    Rgba8,
    Bgra8,
}

The channel order the four bytes of a pixel arrive in, for a consumer reading frames off a pipe or a buffer (ADR-0187).

A closed set of two, because a frame this engine hands out is 8 bits per channel in one of the two orders a swapchain negotiates. sRGB and linear variants of a format are the same order — the transfer function is what a consumer’s own colour handling deals with and the byte layout is what it has to be told.

Variants

Rgba8

Red, green, blue, alpha — what a headless run always produces, and what an ImageData on a canvas means by its bytes.

Bgra8

Blue, green, red, alpha — what a swapchain commonly negotiates on Windows, and the order a consumer assuming the other one paints with red and blue swapped.

Implementations

impl PixelOrder

pub const ALL: [PixelOrder; 2]

Every name, for a consumer enumerating the closed set.

pub fn as_str(self) -> &'static str

The name a frame pipe’s announcement carries.

Trait Implementations

impl Clone for PixelOrder

fn clone(&self) -> PixelOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelOrder

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

Formats the value using the given formatter.

impl PartialEq for PixelOrder

fn eq(&self, other: &PixelOrder) -> 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.
