Trait Notify 

pub trait Notify {
    type Event: Event;
    type NotifyFuture: Future<Output = Result<(), ClosedClient>> + Send + Unpin;

    // Required method
    fn notify(&self, event: Self::Event) -> Self::NotifyFuture;
}

This trait defines how an event should be notified for a client. The struct that implements this trait can hold client specific data.

Required Associated Types

type Event: Event

The type of the event that can be sent through this notification channel.

type NotifyFuture: Future<Output = Result<(), ClosedClient>> + Send + Unpin

The type of the future that will resolve when the client acknowledges the event or the client is lost.

Required Methods

fn notify(&self, event: Self::Event) -> Self::NotifyFuture

If the event was notified successfully, the future should return Ok(()), otherwise if the client is closed, the future should return Err(ClosedClient) which will results in the corresponding client being removed from the event queue.
