Enum DisplayPlaneAlpha

#[repr(u32)]
pub enum DisplayPlaneAlpha {
    Opaque = 1,
    Global = 2,
    PerPixel = 4,
    PrePixelPremultiplied = 8,
}

Available on crate feature VK_KHR_display only.

Alpha blending type

Variants

Opaque = 1

The source image will be treated as opaque

Global = 2

A global alpha value must be specified that will be applied to all pixels in the source image

PerPixel = 4

The alpha value will be determined by the alpha channel of the source image’s pixels. If the source format contains no alpha values, no blending will be applied. The source alpha values are not premultiplied into the source image’s other color channels

PrePixelPremultiplied = 8

This is equivalent to PerPixel except the source alpha values are assumed to be premultiplied into the source image’s other color channels

Trait Implementations

impl Clone for DisplayPlaneAlpha

fn clone(&self) -> DisplayPlaneAlpha

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayPlaneAlpha

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

Formats the value using the given formatter.

impl PartialEq for DisplayPlaneAlpha

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