No ready() -> bool function in FenceSignalFuture

In the codebase I see that Fence has two associated functions: ready(&self) -> Result<bool, OomError> and wait(&self, timeout: Option<Duration>) -> Result<(), FenceWaitError>. When I'm constructing a future like in the examples I'm getting an instance of FenceSignalFuture (after calling then_signal_fence_and_flush).

But I want to keep updating my scene on CPU, while checking each time if previous frame finished rendering and freed access to storage buffers so that I can upload new data to them. For that I wanted to have some function like ready to check if future is ready without blocking the cpu.

Can that be added? If no, then how can I get the behavior I described?
I can try to make a PR for that, but I'm not sure right now if I'm using the API in a correct way, so asking for a suggestion
