}

Pixel format definitions that bridge different versions of sysmem / images2 formats Fuchsia uses for display and GPU drivers’ internal image type representation.

NOTE: The color-components are interpreted in memory in little-endian byte-order. E.g., PixelFormat::Bgra32 as [u8; 4] would have components [blue, green, red, alpha].

Formats the value using the given formatter.

impl Default for PixelFormat

fn default() -> PixelFormat

Returns the “default value” for a type.
