    },
}

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<Access>

The access flags controlling the buffer.

target: &'a <B as Backend>::Buffer

The buffer the barrier controls.

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.

range: Range<Option<u64>>

Range of the buffer the barrier applies to.

Image

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

Fields of Image

states: Range<(Access, Layout)>

The access flags controlling the image.

target: &'a <B as Backend>::Image

The image the barrier controls.

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.

range: SubresourceRange

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

Methods

impl<'a, B> Barrier<'a, B> where
    B: Backend, 

pub fn whole_buffer(
    target: &'a <B as Backend>::Buffer,
    states: Range<Access>
) -> Barrier<'a, B>
