Struct vulkano::sync::FenceSignalFuture [−][src]
pub struct FenceSignalFuture<F> where
F: GpuFuture, { /* fields omitted */ }
Expand description
Represents a fence being signaled after a previous event.
Contrary to most other future types, it is possible to block the current thread until the event
happens. This is done by calling the wait()
function.
Also note that the GpuFuture
trait is implemented on Arc<FenceSignalFuture<_>>
.
This means that you can put this future in an Arc
and keep a copy of it somewhere in order
to know when the execution reached that point.
use std::sync::Arc; use vulkano::sync::GpuFuture; // Assuming you have a chain of operations, like this: // let future = ... // .then_execute(foo) // .then_execute(bar) // You can signal a fence at this point of the chain, and put the future in an `Arc`. let fence_signal = Arc::new(future.then_signal_fence()); // And then continue the chain: // fence_signal.clone() // .then_execute(baz) // .then_execute(qux) // Later you can wait until you reach the point of `fence_signal`: fence_signal.wait(None).unwrap();
Implementations
Blocks the current thread until the fence is signaled by the GPU. Performs a flush if necessary.
If timeout
is None
, then the wait is infinite. Otherwise the thread will unblock after
the specified timeout has elapsed and an error will be returned.
If the wait is successful, this function also cleans any resource locked by previous submissions.
Trait Implementations
If possible, checks whether the submission has finished. If so, gives up ownership of the resources used by these submissions. Read more
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
Flushes the future and submits to the GPU the actions that will permit this future to occur. Read more
Sets the future to its “complete” state, meaning that it can safely be destroyed. Read more
Returns true
if elements submitted after this future can be submitted to a different
queue than the other returned by queue()
. Read more
Returns the queue that triggers the event. Returns None
if unknown or irrelevant. Read more
