Struct wgpu_core::device::life::ActiveSubmission

struct ActiveSubmission<A: Api> {
    index: FenceValue,
    last_resources: NonReferencedResources<A>,
    mapped: Vec<Valid<BufferId>>,
    encoders: Vec<EncoderInFlight<A>>,
    work_done_closures: SmallVec<[SubmittedWorkDoneClosure; 1]>,
}

Resources used by a queue submission, and work to be done once it completes.

Fields

index: FenceValue

The index of the submission we track.

When Device::fence’s value is greater than or equal to this, our queue submission has completed.

last_resources: NonReferencedResources<A>

Resources to be freed once this queue submission has completed.

When the device is polled, for completed submissions, triage_submissions merges these into LifetimeTracker::free_resources. From there, LifetimeTracker::cleanup passes them to the hal to be freed.

This includes things like temporary resources and resources that are used by submitted commands but have been dropped by the user (meaning that this submission is their last reference.)

mapped: Vec<Valid<BufferId>>

Buffers to be mapped once this submission has completed.

encoders: Vec<EncoderInFlight<A>>

work_done_closures: SmallVec<[SubmittedWorkDoneClosure; 1]>

List of queue “on_submitted_work_done” closures to be called once this submission has completed.
