optionsScheduler options that customize this publisher’s delivery of elements.
Return Value

Discussion
Use this operator when you want to wait for a pause in the delivery of events from the upstream publisher. For example, call debounce on the publisher from a text field to only receive elements when the user pauses or stops typing. When they start typing again, the debounce holds event delivery until the next pause.
