pub struct NumericFeatureBufferStore { /* private fields */ }

Implementations

impl NumericFeatureBufferStore

pub fn new(buffers: BTreeMap<String, NumericFeatureBuffer>) -> Result<Self>

pub fn from_feature_tables(tables: Vec<CoordinatorFeatureTable>) -> Result<Self>

pub fn from_f64_matrices(matrices: Vec<NumericFeatureMatrixF64>) -> Result<Self>

pub fn from_f64_column_matrices( matrices: Vec<NumericFeatureMatrixF64Columnar>, ) -> Result<Self>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn get(&self, feature_set_id: &str) -> Option<&NumericFeatureBuffer>

pub fn iter(&self) -> impl Iterator<Item = (&String, &NumericFeatureBuffer)>

Deterministic iteration over (feature_set_id, buffer) pairs in ascending feature_set_id order. Used by the file-store serializer to produce byte-identical output for byte-identical stores.

pub fn manifests(&self) -> Result<Vec<NumericFeatureBufferManifest>>

pub fn bindings_for_relations( &self, relations: &CoordinatorRelationSet, representation_id: &RepresentationId, ) -> Result<Vec<NumericFeatureBufferBinding>>

pub fn project_relations( &self, feature_set_id: &str, relations: &CoordinatorRelationSet, source_id: Option<&SourceId>, columns: Option<&[String]>, ) -> Result<CoordinatorFeatureBlock>

pub fn project_relations_f64( &self, feature_set_id: &str, relations: &CoordinatorRelationSet, source_id: Option<&SourceId>, columns: Option<&[String]>, ) -> Result<CoordinatorFeatureBlockF64>

Trait Implementations

impl Clone for NumericFeatureBufferStore

fn clone(&self) -> NumericFeatureBufferStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericFeatureBufferStore

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

Formats the value using the given formatter.

impl Default for NumericFeatureBufferStore

fn default() -> NumericFeatureBufferStore

Returns the “default value” for a type.

impl PartialEq for NumericFeatureBufferStore

fn eq(&self, other: &NumericFeatureBufferStore) -> 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.
