Struct NdTensorArena 

pub struct NdTensorArena { /* private fields */ }

A store plus per-data-handle bindings, mirroring NumericFeatureBufferArena.

Implementations

impl NdTensorArena

pub fn new(store: NdTensorStore) -> NdTensorArena

pub fn bind_data_handle( &mut self, data_handle: u64, relations: &CoordinatorRelationSet, representation_id: &RepresentationId, ) -> Result<Vec<NdTensorBinding>, DataError>

Binds tensors matching representation_id to data_handle and returns the bindings.

pub fn release_data_handle(&mut self, data_handle: u64) -> bool

pub fn manifests(&self) -> Result<Vec<NdTensorManifest>, DataError>

pub fn bindings_for_data_handle( &self, data_handle: u64, ) -> Result<Vec<NdTensorBinding>, DataError>

pub fn project_bound_relations( &self, data_handle: u64, tensor_id: &str, relations: &CoordinatorRelationSet, source_id: Option<&SourceId>, ) -> Result<NdTensorBlock, DataError>

Projects a bound tensor over relations. Mirrors the feature-buffer bound-source check: the tensor must be bound to data_handle; an explicit source_id must be present in the view AND bound; an unscoped export requires EVERY source present in the view to be bound.

Trait Implementations

impl Clone for NdTensorArena

fn clone(&self) -> NdTensorArena

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NdTensorArena

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

Formats the value using the given formatter.

impl Default for NdTensorArena

fn default() -> NdTensorArena

Returns the “default value” for a type.

impl PartialEq for NdTensorArena

fn eq(&self, other: &NdTensorArena) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
