Struct ControlOutcome 

pub struct ControlOutcome {
    pub stopped: bool,
    pub paused_for: Duration,
}

What draining pending source requests actually did — whether Stop or source-only Finish ended it, and how long (if any) was spent frozen inside a Pause/Resume pair. A source built on wall-clock scheduling (an elapsed-time budget like crate::elements::TestAudioSource/ crate::elements::AudioMixer, or an absolute next-tick deadline like crate::elements::TestVideoSource/DxgiCaptureSource) has to fold paused_for back into its own schedule after every drain_control call — real (Instant) time keeps moving during a Pause, but the media timeline must not, or Resume would look like a burst of catch-up work owed all at once.

Fields

stopped: bool

true if either Stop or source-only Finish was seen: the caller should return Ok(()) immediately. Stop abandons without EOS; Finish has already pushed ordered EOS from the source boundary. Keeping this terminal flag true for both also makes existing custom source loops honor the new graceful request without continuing to emit after EOS.

paused_for: Duration

Wall-clock time from starting the synchronous downstream Pause cascade through finishing the matching Resume (or terminating Stop) cascade during this call — Duration::ZERO if no Pause was seen. Still meaningful even when stopped is true (the sender simply going away while paused is treated the same as Stop, see wait_out_pause), so a caller that also tracks its own paused-time total can fold this in unconditionally rather than only on the non-stopped path.
