schedule()

void MayaFlux::Kriya::Timer::schedule	(	double	delay_seconds,
		std::function< void()>	callback
	)

Schedules a callback to execute after a delay.

Parameters

delay_seconds	Time to wait before executing the callback (in seconds)
callback	Function to execute after the delay

This method schedules the provided callback to execute after exactly the specified delay. If a callback is already scheduled, it is cancelled and replaced with the new one.

The timing is sample-accurate, ensuring that the callback executes at precisely the right moment in the processing timeline.
