Struct EnvelopeAttestedRuntimeDataProvider 

pub struct EnvelopeAttestedRuntimeDataProvider<P> { /* private fields */ }

Owns a host data provider while supplying envelope-backed identities at the runtime trust boundary. A complete training identity is available only when the envelope carries feature, target and relation fingerprints.

Construction validates the complete binding/envelope set before the inner provider can be invoked. Runtime calls are delegated only when their full DataBinding is field-for-field equal to the binding registered for the rendered V1 requirement key.

Implementations

impl<P> EnvelopeAttestedRuntimeDataProvider<P>

pub fn new<I>( inner: P, bindings: I, envelopes: BTreeMap<String, ExternalDataPlanEnvelope>, ) -> Result<EnvelopeAttestedRuntimeDataProvider<P>, DagMlError>

where I: IntoIterator<Item = DataBinding>,

pub fn inner(&self) -> &P

pub fn into_inner(self) -> P

Trait Implementations

impl<P> Debug for EnvelopeAttestedRuntimeDataProvider<P>

where P: Debug,

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

Formats the value using the given formatter.

impl<P> RuntimeDataProvider for EnvelopeAttestedRuntimeDataProvider<P>

where P: RuntimeDataProvider,

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.
