Trait Implementations
impl GpuFuture for NowFuture
[src]
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
unsafe fn build_submission(&self) -> Result<SubmitAnyBuilder, FlushError>
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 more
fn flush(&self) -> Result<(), FlushError>
Flushes the future and submits to the GPU the actions that will permit this future to occur. Read more
unsafe fn signal_finished(&self)
Sets the future to its "complete" state, meaning that it can safely be destroyed. Read more
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()
. Read more
fn queue(&self) -> Option<Arc<Queue>>
Returns the queue that triggers the event. Returns None
if unknown or irrelevant. Read more
fn check_buffer_access(
&self,
buffer: &BufferAccess,
exclusive: bool,
queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, AccessCheckError>
&self,
buffer: &BufferAccess,
exclusive: bool,
queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, 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
fn check_image_access(
&self,
image: &ImageAccess,
layout: ImageLayout,
exclusive: bool,
queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, AccessCheckError>
&self,
image: &ImageAccess,
layout: ImageLayout,
exclusive: bool,
queue: &Queue
) -> Result<Option<(PipelineStages, AccessFlagBits)>, 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
fn join<F>(self, other: F) -> JoinFuture<Self, F> where
Self: Sized,
F: GpuFuture,
Self: Sized,
F: GpuFuture,
Joins this future with another one, representing the moment when both events have happened.
fn then_execute<Cb>(
self,
queue: Arc<Queue>,
command_buffer: Cb
) -> Result<CommandBufferExecFuture<Self, Cb>, CommandBufferExecError> where
Self: Sized,
Cb: CommandBuffer + 'static,
self,
queue: Arc<Queue>,
command_buffer: Cb
) -> Result<CommandBufferExecFuture<Self, Cb>, CommandBufferExecError> where
Self: Sized,
Cb: CommandBuffer + 'static,
Executes a command buffer after this future. Read more
fn then_execute_same_queue<Cb>(
self,
command_buffer: Cb
) -> Result<CommandBufferExecFuture<Self, Cb>, CommandBufferExecError> where
Self: Sized,
Cb: CommandBuffer + 'static,
self,
command_buffer: Cb
) -> Result<CommandBufferExecFuture<Self, Cb>, CommandBufferExecError> where
Self: Sized,
Cb: CommandBuffer + 'static,
Executes a command buffer after this future, on the same queue as the future. Read more
fn then_signal_semaphore(self) -> SemaphoreSignalFuture<Self> where
Self: Sized,
Self: Sized,
Signals a semaphore after this future. Returns another future that represents the signal. Read more
fn then_signal_semaphore_and_flush(
self
) -> Result<SemaphoreSignalFuture<Self>, FlushError> where
Self: Sized,
self
) -> Result<SemaphoreSignalFuture<Self>, FlushError> where
Self: Sized,
Signals a semaphore after this future and flushes it. Returns another future that represents the moment when the semaphore is signalled. Read more
fn then_signal_fence(self) -> FenceSignalFuture<Self> where
Self: Sized,
Self: Sized,
Signals a fence after this future. Returns another future that represents the signal. Read more
fn then_signal_fence_and_flush(
self
) -> Result<FenceSignalFuture<Self>, FlushError> where
Self: Sized,
self
) -> Result<FenceSignalFuture<Self>, FlushError> where
Self: Sized,
Signals a fence after this future. Returns another future that represents the signal. Read more
fn then_swapchain_present(
self,
queue: Arc<Queue>,
swapchain: Arc<Swapchain>,
image_index: usize
) -> PresentFuture<Self> where
Self: Sized,
self,
queue: Arc<Queue>,
swapchain: Arc<Swapchain>,
image_index: usize
) -> PresentFuture<Self> where
Self: Sized,
Presents a swapchain image after this future. Read more
