Struct LaggedSamplePlan 

pub struct LaggedSamplePlan { /* private fields */ }

Reusable plan for gathering a fixed set of lagged columns.

Implementations

impl LaggedSamplePlan

pub fn new( series_len: usize, max_lag: u32, columns: impl Into<Arc<[LaggedColumn]>>, ) -> Result<Self, DataError>

Plan lagged columns for a series length / max lag (series-origin reference).

Errors

Invalid lag map, empty column list, or a column lag exceeding max_lag.

pub fn with_reference( series_len: usize, max_lag: u32, reference: ReferencePointPolicy, columns: impl Into<Arc<[LaggedColumn]>>, ) -> Result<Self, DataError>

Plan lagged columns under an explicit reference-point policy.

Errors

Invalid lag map, empty column list, or a column lag exceeding max_lag.

pub fn with_shared( lag_map: Arc<LagMap>, columns: Arc<[LaggedColumn]>, ) -> Result<Self, DataError>

Build a plan that reuses a shared lag map and column list (multi-env / panel).

Errors

Empty column list, or a column lag exceeding the shared map’s max_lag.

pub fn columns(&self) -> &[LaggedColumn]

Planned columns.

pub fn columns_arc(&self) -> &Arc<[LaggedColumn]>

Shared column Arc (for multi-env plan reuse).

pub fn lag_map(&self) -> &LagMap

Lag map.

pub fn lag_map_arc(&self) -> &Arc<LagMap>

Shared lag-map Arc (identical lengths can share one map).

pub fn n_effective(&self) -> usize

Effective sample size.

pub fn prepare<'a>( &'a self, data: &TimeSeriesData, workspace: &'a mut LaggedSampleWorkspace, policy: &KernelPolicy, ) -> Result<LaggedPreparedSample<'a>, DataError>

Gather planned columns into workspace (grows once, then reuses capacity).

Errors

Missing / non-float64 columns, series length mismatch, or incomplete series (missing values or a row-hiding analysis mask).
