Reusable compiled sample plan.

Fields

columns: Vec<PreparedColumn>

Prepared column descriptors in matrix order (X then Y then Z).

row_selector: PreparedRowSelector

Row selector recipe.

output_layout: SampleLayout

Output layout.

cache_key: SampleCacheKey

Cache key.

partitions: SamplePartitions

Partitions.

Implementations

impl SamplePlan

pub fn compile_tabular( data: &TabularData, request: &SampleRequest<'_>, ) -> Result<Self, DataError>

Compile a plan against tabular (IID) data. Lagged nodes are rejected.

Errors

Empty request, lagged nodes, unknown variables, or empty selection.

pub fn compile_timeseries( data: &TimeSeriesData, request: &SampleRequest<'_>, ) -> Result<Self, DataError>

Compile a plan against a regular time series (supports lagged nodes).

Errors

Irregular series, empty request, unknown variables, or invalid lags.

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

Planned columns.

pub fn cache_key(&self) -> &SampleCacheKey

Cache key.

pub fn prepare<'a>( &'a self, data: &impl TableView, storage_mask: Option<&ValidityBitmap>, storage_weights: Option<&[f64]>, workspace: &'a mut SampleWorkspace, policy: &KernelPolicy, ) -> Result<PreparedSample<'a>, DataError>

Materialize into workspace.

Errors

Missing columns, empty selection after policies, or type mismatches.

pub fn prepare_tabular<'a>( &'a self, data: &TabularData, workspace: &'a mut SampleWorkspace, policy: &KernelPolicy, ) -> Result<PreparedSample<'a>, DataError>

Prepare from TabularData.

Errors

Propagates Self::prepare errors.

pub fn prepare_timeseries<'a>( &'a self, data: &TimeSeriesData, workspace: &'a mut SampleWorkspace, policy: &KernelPolicy, ) -> Result<PreparedSample<'a>, DataError>

Prepare from TimeSeriesData.

Errors

Propagates Self::prepare errors.
