pub struct ImageAccessFromUndefinedLayout<I> { /* private fields */ }
Expand description
Wraps around an object that implements ImageAccess
and modifies the initial layout
requirement to be either Undefined
or Preinitialized
.

sourcefn inner(&self) -> ImageInner<'_>
fn inner(&self) -> ImageInner<'_>
Returns the inner unsafe image object used by this image.
sourcefn initial_layout_requirement(&self) -> ImageLayout
fn initial_layout_requirement(&self) -> ImageLayout
Returns the layout that the image has when it is first used in a primary command buffer. Read more
sourcefn final_layout_requirement(&self) -> ImageLayout
fn final_layout_requirement(&self) -> ImageLayout

sourcefn descriptor_layouts(&self) -> Option<ImageDescriptorLayouts>
fn descriptor_layouts(&self) -> Option<ImageDescriptorLayouts>
Returns an ImageDescriptorLayouts
structure specifying the image layout to use
in descriptors of various kinds. Read more
sourcefn conflict_key(&self) -> u64
fn conflict_key(&self) -> u64
Returns a key that uniquely identifies the memory content of the image. Two ranges that potentially overlap in memory must return the same key. Read more

exclusive_access: bool,
uninitialized_safe: bool,
expected_layout: ImageLayout
) -> Result<(), AccessError>
fn try_gpu_lock(
&self,
exclusive_access: bool,
uninitialized_safe: bool,
expected_layout: ImageLayout
) -> Result<(), AccessError>
Locks the resource for usage on the GPU. Returns an error if the lock can’t be acquired. Read more
sourceunsafe fn increase_gpu_lock(&self)
unsafe fn increase_gpu_lock(&self)
Locks the resource for usage on the GPU. Supposes that the resource is already locked, and simply increases the lock by one. Read more
sourceunsafe fn unlock(&self, new_layout: Option<ImageLayout>)
unsafe fn unlock(&self, new_layout: Option<ImageLayout>)
Unlocks the resource previously acquired with try_gpu_lock
or increase_gpu_lock

sourcefn current_mip_levels_access(&self) -> Range<u32>
fn current_mip_levels_access(&self) -> Range<u32>
Returns the current mip level that is accessed by the gpu
sourcefn current_array_layers_access(&self) -> Range<u32>
fn current_array_layers_access(&self) -> Range<u32>
Returns the current array layer that is accessed by the gpu
sourcefn mip_levels(&self) -> u32
fn mip_levels(&self) -> u32
Returns the number of mipmap levels of this image.
sourcefn samples(&self) -> SampleCount
fn samples(&self) -> SampleCount
Returns the number of samples of this image.
sourcefn dimensions(&self) -> ImageDimensions
fn dimensions(&self) -> ImageDimensions
Returns the dimensions of the image.
sourcefn format_features(&self) -> &FormatFeatures
fn format_features(&self) -> &FormatFeatures
Returns the features supported by the image’s format.
sourceunsafe fn layout_initialized(&self)
unsafe fn layout_initialized(&self)
When images are created their memory layout is initially Undefined
or Preinitialized
.
This method allows the image memory barrier creation process to signal when an image
has been transitioned out of its initial Undefined
or Preinitialized
state. This
allows vulkano to avoid creating unnecessary image memory barriers between future
uses of the image. Read more
