Trait Implementations

impl AcceptArrayVisitor for NullArray

fn accept(&self, visitor: &mut dyn ArrayVisitor) -> VortexResult<()>

impl ArrayCompute for NullArray

fn scalar_at(&self) -> Option<&dyn ScalarAtFn>

Single item indexing on Vortex arrays.

fn slice(&self) -> Option<&dyn SliceFn>

Perform zero-copy slicing of an array.

fn take(&self) -> Option<&dyn TakeFn>

Take a set of indices from an array. This often forces allocations and decoding of the receiver.

fn cast(&self) -> Option<&dyn CastFn>

Implemented for arrays that can be casted to different types.

fn compare(&self) -> Option<&dyn CompareFn>

Binary operator implementation for arrays against other arrays.

fn fill_forward(&self) -> Option<&dyn FillForwardFn>

Array function that returns new arrays a non-null value is repeated across runs of nulls.

fn filter(&self) -> Option<&dyn FilterFn>

Filtering function on arrays of predicates.

fn filter_indices(&self) -> Option<&dyn FilterIndicesFn>

Filter indices based on a disjunctive normal form relational expression. TODO(aduffy): remove this function and push implementation into vortex-datafusion.

fn subtract_scalar(&self) -> Option<&dyn SubtractScalarFn>

Broadcast subtraction of scalar from Vortex array.
