Function vector::event::into_event_stream

pub fn into_event_stream(
    container: impl EventContainer,
) -> impl Stream<Item = Event> + Unpin

Turn a container into a futures stream over the contained Event type. This would ideally be implemented as a default method on trait EventContainer, but the required feature (associated type defaults) is still unstable. See https://github.com/rust-lang/rust/issues/29661
