Required Methods

fn new<F>(target: Option<WidgetId>, task: F) -> Self

where F: Future<Output = R> + Send + 'static,

Create a UI bound future executor.

The task is inert and must be polled using update to start, and it must be polled every UiNode::update after that, in widgets the target can be set so that the update requests are received.
