Enum ReferencePointPolicy 

pub enum ReferencePointPolicy {
    SeriesOrigin,
    AbsoluteOrigin {
        origin_row: usize,
    },
}

How lag-aligned samples choose their contemporaneous origin row.

Variants

SeriesOrigin

Origin at row max_lag so every lag in 0..=max_lag is in-bounds (default stationary series alignment).

AbsoluteOrigin

Absolute origin row; effective samples are origin_row .. series_len clipped so lags stay in-bounds.

Fields

origin_row: usize

Row treated as contemporaneous lag-0.

Implementations

impl ReferencePointPolicy

pub fn base_and_n( self, series_len: usize, max_lag: u32, ) -> Result<(usize, usize), DataError>

Base contemporaneous row and effective sample count for a series.

Errors

Empty series, max_lag too large, or origin out of range.
