Enum vulkano::display::DisplayPlaneAlpha

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

The alpha blending mode to use for a display mode.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Opaque = 1

The source image is treated as opaque.

Global = 2

Use a single global alpha value that will be used for all pixels in the source image.

PerPixel = 4

Use the alpha component of each pixel in the source image.

PerPixelPremultiplied = 8

Use the alpha component of each pixel in the source image, but treat the other components as having already been multiplied by the alpha component.

Trait Implementations

impl Clone for DisplayPlaneAlpha

fn clone(&self) -> DisplayPlaneAlpha

Returns a copy 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 From<DisplayPlaneAlpha> for DisplayPlaneAlphaFlags

fn from(val: DisplayPlaneAlpha) -> Self

Converts to this type from the input type.

impl From<DisplayPlaneAlpha> for DisplayPlaneAlphaFlagsKHR

fn from(val: DisplayPlaneAlpha) -> Self

Converts to this type from the input type.

impl FromIterator<DisplayPlaneAlpha> for DisplayPlaneAlphaFlags

fn from_iter<T>(iter: T) -> Selfwhere T: IntoIterator<Item = DisplayPlaneAlpha>,

Creates a value from an iterator.

impl Hash for DisplayPlaneAlpha

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DisplayPlaneAlpha

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

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

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 TryFrom<DisplayPlaneAlphaFlagsKHR> for DisplayPlaneAlpha

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: DisplayPlaneAlphaFlagsKHR) -> Result<Self, Self::Error>

Performs the conversion.
