Enum wgpu_types::Maintain

source · [−]

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

Expand description

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.

Implementations
