Trait Implementations

impl ArrayVTable<FixedSizeListVTable> for FixedSizeListVTable

fn len(array: &FixedSizeListArray) -> usize

fn dtype(array: &FixedSizeListArray) -> &DType

fn stats(array: &FixedSizeListArray) -> StatsSetRef<'_>

impl CanonicalVTable<FixedSizeListVTable> for FixedSizeListVTable

fn canonicalize(array: &FixedSizeListArray) -> Canonical

Returns the canonical representation of the array.

fn append_to_builder(array: &V::Array, builder: &mut dyn ArrayBuilder)

Writes the array into a canonical builder.

impl CastKernel for FixedSizeListVTable

Cast implementation for FixedSizeListArray.

Recursively casts the inner elements array to the target element type while preserving the list structure.

fn cast( &self, array: &FixedSizeListArray, dtype: &DType, ) -> VortexResult<Option<ArrayRef>>

impl Debug for FixedSizeListVTable

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

Formats the value using the given formatter.

impl FilterKernel for FixedSizeListVTable

Filter implementation for FixedSizeListArray.

Expands the selection mask to cover all elements within selected lists and pushes the expanded mask down to the child elements array.

fn filter( &self, array: &FixedSizeListArray, selection_mask: &Mask, ) -> VortexResult<ArrayRef>

Filter an array by the provided predicate.

impl IsConstantKernel for FixedSizeListVTable

IsConstant implementation for FixedSizeListArray.

Compares each list scalar against the first to determine if all lists are identical.

fn is_constant( &self, array: &FixedSizeListArray, _opts: &IsConstantOpts, ) -> VortexResult<Option<bool>>

Preconditions

impl IsSortedKernel for FixedSizeListVTable

IsSorted implementation for FixedSizeListArray.

fn is_sorted(&self, _array: &FixedSizeListArray) -> VortexResult<Option<bool>>

Preconditions

fn is_strict_sorted( &self, _array: &FixedSizeListArray, ) -> VortexResult<Option<bool>>

impl MaskKernel for FixedSizeListVTable

Mask implementation for FixedSizeListArray.

Applies a validity mask to the array without modifying the underlying element data.

fn mask( &self, array: &FixedSizeListArray, mask: &Mask, ) -> VortexResult<ArrayRef>

Replace masked values with null in array.

impl MinMaxKernel for FixedSizeListVTable

MinMax implementation for FixedSizeListArray.

fn min_max( &self, _array: &FixedSizeListArray, ) -> VortexResult<Option<MinMaxResult>>

impl OperationsVTable<FixedSizeListVTable> for FixedSizeListVTable

fn slice(array: &FixedSizeListArray, range: Range<usize>) -> ArrayRef

Perform a constant-time slice of the array.

fn scalar_at(array: &FixedSizeListArray, index: usize) -> Scalar

Fetch the scalar at the given index.

impl SerdeVTable<FixedSizeListVTable> for FixedSizeListVTable

fn build( _encoding: &FixedSizeListEncoding, dtype: &DType, len: usize, _metadata: &EmptyMetadata, buffers: &[ByteBuffer], children: &dyn ArrayChildren, ) -> VortexResult<FixedSizeListArray>

Builds a FixedSizeListArray.

This method expects 1 or 2 children (a second child indicates a validity array).

type Metadata = EmptyMetadata

fn metadata(_array: &FixedSizeListArray) -> VortexResult<Option<Self::Metadata>>

Exports metadata for an array.

impl TakeKernel for FixedSizeListVTable

Take implementation for FixedSizeListArray.

Unlike ListView, FixedSizeListArray must rebuild the elements array because it requires that elements start at offset 0 and be perfectly packed without gaps. We expand list indices into element indices and push them down to the child elements array.

fn take( &self, array: &FixedSizeListArray, indices: &dyn Array, ) -> VortexResult<ArrayRef>

Create a new array by taking the values from the array at the given indices.

impl VTable for FixedSizeListVTable

type Array = FixedSizeListArray

type Encoding = FixedSizeListEncoding

type ArrayVTable = FixedSizeListVTable

type CanonicalVTable = FixedSizeListVTable

type OperationsVTable = FixedSizeListVTable

type ValidityVTable = ValidityVTableFromValidityHelper

type VisitorVTable = FixedSizeListVTable

type ComputeVTable = NotSupported

Optionally enable implementing dynamic compute dispatch for this encoding. Can be disabled by assigning to the NotSupported type.

type EncodeVTable = NotSupported

Optionally enable the EncodeVTable for this encoding. This allows it to partake in compression. Can be disabled by assigning to the NotSupported type.

type PipelineVTable = NotSupported

Optionally enable the PipelineVTable for this encoding. This allows it to partake in operator operations.

type SerdeVTable = FixedSizeListVTable

Optionally enable serde for this encoding by implementing the SerdeVTable trait. Can be disabled by assigning to the NotSupported type.

fn id(_encoding: &Self::Encoding) -> EncodingId

Returns the ID of the encoding.

fn encoding(_array: &Self::Array) -> EncodingRef

Returns the encoding for the array.

impl VisitorVTable<FixedSizeListVTable> for FixedSizeListVTable

fn visit_buffers( _array: &FixedSizeListArray, _visitor: &mut dyn ArrayBufferVisitor, )

Visit the buffers of the array.

fn visit_children( array: &FixedSizeListArray, visitor: &mut dyn ArrayChildVisitor, )

Visit the children of the array.

fn nbuffers(array: &V::Array) -> usize

Count the number of buffers in the array.

fn nchildren(array: &V::Array) -> usize

Count the number of children in the array.
