Struct vulkano::image::traits::ImageAccessFromUndefinedLayout [−][src]
pub struct ImageAccessFromUndefinedLayout<I> { /* fields omitted */ }
Expand description
Wraps around an object that implements ImageAccess
and modifies the initial layout
requirement to be either Undefined
or Preinitialized
.
Trait Implementations
Returns the inner unsafe image object used by this image.
Returns the layout that the image has when it is first used in a primary command buffer. Read more
Returns the layout that the image must be returned to before the end of the command buffer. Read more
Returns an ImageDescriptorLayouts
structure specifying the image layout to use
in descriptors of various kinds. Read more
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,

) -> 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
Locks the resource for usage on the GPU. Supposes that the resource is already locked, and simply increases the lock by one. Read more
Unlocks the resource previously acquired with try_gpu_lock
or increase_gpu_lock
. Read more
Returns the current mip level that is accessed by the gpu
Returns the current layer level that is accessed by the gpu
Returns the number of mipmap levels of this image.
Returns the number of samples of this image.
Returns the dimensions of the image.
Returns true if the image can be used as a source for blits.
Returns true if the image can be used as a destination for blits.
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
