Struct DriftEstimator 

pub struct DriftEstimator { /* private fields */ }

Drift estimator using integer linear regression over recent measurements.

Tracks (time, offset) pairs and computes drift rate in parts-per-million (PPM) using integer arithmetic only.

Implementations

impl DriftEstimator

pub fn new() -> Self

Create a new drift estimator.

pub fn add(&mut self, elapsed_ms: u64, offset_ms: i64)

Add a data point: elapsed time in ms since first measurement, and offset in ms.

pub fn drift_ppb(&self) -> Option<i64>

Compute drift rate in parts-per-billion (PPB) using integer-only linear regression (slope = sum(dx*dy) / sum(dx^2)).

Returns None if fewer than 2 samples.

Trait Implementations

impl Debug for DriftEstimator

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

Formats the value using the given formatter.

impl Default for DriftEstimator

fn default() -> Self

Returns the “default value” for a type.
