Struct datafusion_physical_expr::equivalence::OrderingEquivalenceBuilder

pub struct OrderingEquivalenceBuilder { /* private fields */ }

This is a builder object facilitating incremental construction for ordering equivalences.

Implementations

impl OrderingEquivalenceBuilder

pub fn with_equivalences(self, new_eq_properties: EquivalenceProperties) -> Self

pub fn add_equal_conditions( &mut self, new_equivalent_ordering: Vec<PhysicalSortExpr> )

pub fn schema(&self) -> &SchemaRef

Return a reference to the schema with which this builder was constructed with

pub fn existing_ordering(&self) -> &LexOrdering

Return a reference to the existing ordering
