The item that is yielded in the Streams returned from subscribe.

fn subscribe<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<Pin<Box<dyn Stream<Item = Self::Item> + Send + Sync + 'static>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

If the subscription is still active, returns a new single consumer Stream which would produce a stream of items that are produced after the method is called.
