Enum wgpu_types::Maintain

pub enum Maintain<T> {
    WaitForSubmissionIndex(T),
    Wait,
    Poll,
}

Passed to Device::poll to control how and if it should block.

Variants

WaitForSubmissionIndex(T)

On native backends, block until the given submission has completed execution, and any callbacks have been invoked.

On the web, this has no effect. Callbacks are invoked from the window event loop.

Wait

Same as WaitForSubmissionIndex but waits for the most recent submission.

Poll

Check the device for a single time without blocking.
