    },
}

A memory barrier type for either buffers or images.

Variants

AllBuffers(Range<Access>)

Applies the given access flags to all buffers in the range.

AllImages(Range<Access>)

Applies the given access flags to all images in the range.

Buffer

A memory barrier that defines access to a buffer.

Fields of Buffer

states: Range<State>

The access flags controlling the buffer.

target: &'a B::Buffer

The buffer the barrier controls.

range: SubRange

Subrange of the buffer the barrier applies to.

families: Option<Range<QueueFamilyId>>

The source and destination Queue family IDs, for a queue family ownership transfer Can be None to indicate no ownership transfer.

Image

A memory barrier that defines access to (a subset of) an image.

Fields of Image

states: Range<State>

The access flags controlling the image.

target: &'a B::Image

The image the barrier controls.

range: SubresourceRange

A SubresourceRange that defines which section of an image the barrier applies to.

families: Option<Range<QueueFamilyId>>

The source and destination Queue family IDs, for a queue family ownership transfer Can be None to indicate no ownership transfer.

Methods
