Struct Filter

pub struct Filter<TS: ThreadSafety> { /* private fields */ }

The filter for passing events to async contexts.

This type takes events and passes them to the event handlers. It also handles the async contexts that are waiting for events.

Implementations

impl<TS: ThreadSafety> Filter<TS>

pub fn new(inner: &EventLoop<Wakeup>) -> Filter<TS>

Create a new filter from an event loop.

The future is polled once before returning to set up event handlers.

pub fn handle_event<F>( &mut self, future: Pin<&mut F>, event: Event<'_, Wakeup>, elwt: &EventLoopWindowTarget<Wakeup>, flow: &mut ControlFlow, ) -> ReturnOrFinish<(), F::Output>

where F: Future,

Handle an event.

This function will block on the future if it is in the holding pattern.
