Enum RetryWake 

#[non_exhaustive]
pub enum RetryWake {
    Now,
    After(Duration),
    OnEvent,
}

When the caller should try Gpu::try_acquire_frame again after a FrameAcquire::Skip.

The caller owns the event loop, so it turns this into its own wake-up — e.g. Window::request_redraw for RetryWake::Now, a ControlFlow::WaitUntil deadline for RetryWake::After, nothing for RetryWake::OnEvent. None of them should keep a reactive loop polling.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Now

Retry on the next frame (a Timeout, a surface that is still stale right after a reconfigure, or the immediate first retry of a failed configure).

After(Duration)

A failed configure is backing off: retry no sooner than this.

OnEvent

Do not self-schedule a retry: wait for the next window event. The window is Occluded (a redraw request when it becomes visible again brings the frame back) or the acquire hit a validation error that a redraw loop would only repeat.
