Struct CompositeAlphaFlags 

pub struct CompositeAlphaFlags(/* private fields */);

Available on crate feature VK_KHR_surface only.

Alpha compositing modes supported on a device

Implementations

impl CompositeAlphaFlags

pub const fn bits(&self) -> VkCompositeAlphaFlagsKHR

Returns bits in this flags

pub const fn has_any(self, other: Self) -> bool

Returns true if any of specified bits are contained in this flag.

pub const fn has_all(self, other: Self) -> bool

Returns true if all of specified bits are contained in this flag.

pub const fn merge(self, other: Self) -> Self

merge two flags (const alias of BitOr)

impl CompositeAlphaFlags

pub const OPAQUE: Self

The alpha channel, if it exists, of the image is ignored in the compositing process

pub const PRE_MULTIPLIED: Self

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are expected to already be multiplied by the alpha channel by the application

pub const POST_MULTIPLIED: Self

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are not expected to already be multiplied by the alpha channel by the application; instead, the compositor will multiply the non-alpha channels of the image by the alpha channel during compositing

pub const INHERIT: Self

The way in which the presentation engine treats the alpha channel in the images is unknown to the Vulkan API. Instead, the application is responsible for setting the composite alpha blending mode using native window system commands
