Struct DriftSample 

pub struct DriftSample {
    pub wall_time_secs: f64,
    pub observed_frames: u64,
    pub expected_frames: u64,
}

A drift measurement sample: the observed timecode vs expected timecode at a given wall time.

Fields

wall_time_secs: f64

Wall-clock time in seconds since the measurement started.

observed_frames: u64

Observed frame count from the timecode source.

expected_frames: u64

Expected frame count from the reference clock.

Implementations

impl DriftSample

pub fn new( wall_time_secs: f64, observed_frames: u64, expected_frames: u64, ) -> Self

Creates a new drift sample.

pub fn drift_frames(&self) -> i64

Returns the drift in frames (observed - expected). Positive means ahead.

pub fn drift_ratio(&self) -> f64

Returns the drift as a fraction of the expected frames.

Trait Implementations

impl Clone for DriftSample

fn clone(&self) -> DriftSample

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DriftSample

impl Debug for DriftSample

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DriftSample

fn eq(&self, other: &DriftSample) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
