Description:
 def defer( self, func: typing.Callable[[], typing.Any], until: typing.Union[int, float]=-1, ) -> typing.Any: """Defer the execution of a function until some clock value. Args: func (typing.Callable[[], typing.Any]):
 A callable that accepts no arguments. All return values are ignored. until (typing.Union[int, float]):
 A numeric value that represents the clock time when the callback becomes available for execution. Values that are less than the current time result in the function being called at the next opportunity. Returns: typing.Any: An opaque identifier that represents the callback uniquely within the processor. This identifier is used to modify the callback scheduling. Note: The time given should not be considered absolute. It represents the time when the callback becomes available to execute. It may be much later than the given time value when the function actually executes depending on the implementation. """
