Enum Interpolator 

pub enum Interpolator {
    Linear,
    Nearest,
    CatmullRom,
    Zero,
    Forward,
    Nocb,
}

Interpolation strategy for gap filling.

Variants

Linear

Linearly interpolated values between known points.

Nearest

Nearest neighbor fill.

CatmullRom

Catmull-Rom spline (C1 local interpolation using 4 surrounding points, falls back to Linear).

Monotonic timestamps requirement

The Catmull-Rom interpolation assumes that input timestamps are strictly monotonically increasing. If timestamps are out-of-order or contain duplicates, the interpolated values will be incorrect (the parametric t fraction becomes negative or

1). Callers should sort / deduplicate timestamps before interpolation, or apply ClockDriftStrategy::Monotonic correction first.

Zero

Fill with 0.0.

Forward

Last known value carried forward.

Nocb

Next observation carried backward (Nocb).

Implementations

impl Interpolator

pub fn fill( &self, timestamps: &[i64], values: &[f64], expected_interval_ns: i64, ) -> Result<(Vec<i64>, Vec<f64>, usize, usize), InterpolationError>

Fills gaps in the data using this interpolation method.

timestamps and values are the original (sparse) data. expected_interval_ns is the expected interval between points.

Returns (filled_timestamps, filled_values, gaps_filled_count, gaps_skipped_count).

gaps_skipped_count reports how many gap segments exceeded MAX_GAP_FILL and were left unfilled, so callers can detect incomplete interpolation without parsing logs.
