Struct ClockNormalizer 

pub struct ClockNormalizer { /* private fields */ }

Normalizes device PTS to the shared monotonic clock.

Records the device PTS origin and monotonic clock origin on the first sample. Later calls return device_pts - device_origin + monotonic_origin, shifting the device clock onto the monotonic timeline while preserving its rate.

For sources without device PTS, such as microphones, pass each sample’s arrival time (monotonic_now_ns) as device_pts.

Implementations

impl ClockNormalizer

pub fn new() -> Self

Creates a normalizer with unset origins, which are fixed by the first normalize.

pub fn is_unset(&self) -> bool

Returns whether the origins are still unset (the first sample has not arrived).

pub fn normalize(&mut self, device_pts_ns: i64) -> i64

Maps device PTS (ns) to normalized monotonic PTS (ns).

The first call fixes the origins and uses the current monotonic_now_ns as the monotonic origin. Later calls preserve device-clock deltas. Device rollover uses wrapping subtraction; a translated value outside i64 saturates at the nearest boundary rather than panicking or wrapping the timeline.
