fn init<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), StreamError>> + Send + 'async_trait>>

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

Initialize the operator

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

Called when a window is triggered (if windowing is enabled)

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), StreamError>> + Send + 'async_trait>>
