associated timestamps • Iteration Operators define sequences of events or processing that satisfies a loop condition. • not commonly supported • a termination condition must be defined, e.g. time limit (handle, stream) = scope.loop_variable(100, 1);
 (0..10).to_stream(scope)
 .concat(&stream)
 .inspect(|x| println!("seen: {:?}", x))
 .connect_loop(handle);
