Enum 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 wgpu-core based backends, block until the given submission has completed execution, and any callbacks have been invoked.

On WebGPU, 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

impl<T> Maintain<T>

pub fn wait() -> Self

pub fn is_wait(&self) -> bool

This maintain represents a wait of some kind.

pub fn map_index<U, F>(self, func: F) -> Maintain<U>

where F: FnOnce(T) -> U,
