source§fn cleanup_finished(&mut self)
fn cleanup_finished(&mut self)
If possible, checks whether the submission has finished. If so, gives up ownership of the
resources used by these submissions. Read more
source§unsafe fn build_submission(
&self
) -> Result<SubmitAnyBuilder, Validated<VulkanError>>
unsafe fn build_submission( &self ) -> Result<SubmitAnyBuilder, Validated<VulkanError>>
Builds a submission that, if submitted, makes sure that the event represented by this
GpuFuture
will happen, and possibly contains extra elements (eg. a semaphore wait or an
event wait) that makes the dependency with subsequent operations work. Read moresource§fn flush(&self) -> Result<(), Validated<VulkanError>>
fn flush(&self) -> Result<(), Validated<VulkanError>>
Flushes the future and submits to the GPU the actions that will permit this future to
occur. Read more
source§unsafe fn signal_finished(&self)
unsafe fn signal_finished(&self)
Sets the future to its “complete” state, meaning that it can safely be destroyed. Read more
source§fn queue_change_allowed(&self) -> bool
fn queue_change_allowed(&self) -> bool
Returns
true
if elements submitted after this future can be submitted to a different
queue than the other returned by queue()
.source§fn queue(&self) -> Option<Arc<Queue>>
fn queue(&self) -> Option<Arc<Queue>>
Returns the queue that triggers the event. Returns
None
if unknown or irrelevant. Read moresource§fn check_buffer_access(
&self,
_buffer: &Buffer,
_range: Range<DeviceSize>,
_exclusive: bool,
_queue: &Queue
) -> Result<(), AccessCheckError>
fn check_buffer_access( &self, _buffer: &Buffer, _range: Range<DeviceSize>, _exclusive: bool, _queue: &Queue ) -> Result<(), AccessCheckError>
Checks whether submitting something after this future grants access (exclusive or shared,
depending on the parameter) to the given buffer on the given queue. Read more

&self,
_image: &Image,
_range: Range<DeviceSize>,

fn check_image_access( &self, _image: &Image, _range: Range<DeviceSize>, _exclusive: bool, _expected_layout: ImageLayout, _queue: &Queue ) -> Result<(), AccessCheckError>
Checks whether submitting something after this future grants access (exclusive or shared,
depending on the parameter) to the given image on the given queue. Read more
source§fn check_swapchain_image_acquired(
&self,
_swapchain: &Swapchain,
_image_index: u32,
_before: bool
) -> Result<(), AccessCheckError>
fn check_swapchain_image_acquired( &self, _swapchain: &Swapchain, _image_index: u32, _before: bool ) -> Result<(), AccessCheckError>
Checks whether accessing a swapchain image is permitted. Read more

Self: Sized,
F: GpuFuture,
fn join<F>(self, other: F) -> JoinFuture<Self, F>where Self: Sized, F: GpuFuture,
Joins this future with another one, representing the moment when both events have happened.
