Struct MethodsPlsPredictDataProvider 

pub struct MethodsPlsPredictDataProvider { /* private fields */ }

Native, in-memory data provider for target-free Methods PLS PREDICT.

It is deliberately PREDICT-only: training must use a provider that can produce the complete target-bound [TrainingDataIdentity]. The provider owns only row-major values already materialized by the upstream IO layer; it delegates data/view handles and envelope identity checks to the normal runtime provider rather than bypassing the scheduler.

Implementations

impl MethodsPlsPredictDataProvider

pub fn new<I>( owner_controller: ControllerId, bindings: I, envelopes: BTreeMap<String, ExternalDataPlanEnvelope>, inputs: BTreeMap<String, MethodsPlsPredictInput>, ) -> Result<MethodsPlsPredictDataProvider, DagMlError>

where I: IntoIterator<Item = DataBinding>,

Trait Implementations

impl Debug for MethodsPlsPredictDataProvider

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

Formats the value using the given formatter.

impl RuntimeDataProvider for MethodsPlsPredictDataProvider

fn materialize( &self, request: &DataMaterializationRequest, ) -> Result<HandleRef, DagMlError>

fn make_view(&self, request: &DataViewRequest) -> Result<HandleRef, DagMlError>

fn training_data_identity( &self, binding: &DataBinding, ) -> Result<Option<TrainingDataIdentity>, DagMlError>

Attest the exact feature and target content bound to one training input.

fn coordinator_relations( &self, binding: &DataBinding, ) -> Result<Option<SampleRelationSet>, DagMlError>

fn methods_pls_capability(&self) -> Result<(), DagMlError>

Confirm that this provider can supply the deliberately narrow numeric view consumed by the portable Methods PLS controller. The default is a refusal, so an ordinary data provider can never accidentally expose its buffers to a native numerical controller.

fn preflight_methods_pls( &self, request: &MethodsPlsDataRequest, ) -> Result<(), DagMlError>

fn methods_pls_data( &self, request: &MethodsPlsDataRequest, ) -> Result<MethodsPlsData, DagMlError>

Return provider-selected row-major numeric values for a Methods PLS invocation. This is not a raw IO escape hatch: the request carries the scheduler-created, identity-keyed data views and the provider is solely responsible for resolving them to rows and targets.
