impl CanonicalVTable<ArrowVTable> for ArrowVTable

fn canonicalize(array: &ArrowArray) -> VortexResult<Canonical>

Returns the canonical representation of the array.

fn append_to_builder( array: &V::Array, builder: &mut dyn ArrayBuilder, ) -> VortexResult<()>

Writes the array into a canonical builder.

impl Debug for ArrowVTable

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

Formats the value using the given formatter.

impl OperationsVTable<ArrowVTable> for ArrowVTable

fn slice( array: &ArrowArray, start: usize, stop: usize, ) -> VortexResult<ArrayRef>

Perform a constant-time slice of the array.

fn scalar_at(_array: &ArrowArray, _index: usize) -> VortexResult<Scalar>

impl VTable for ArrowVTable

type Array = ArrowArray

type Encoding = ArrowEncoding

type ArrayVTable = ArrowVTable

type CanonicalVTable = ArrowVTable

type OperationsVTable = ArrowVTable

type ValidityVTable = ArrowVTable

type VisitorVTable = ArrowVTable

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 SerdeVTable = NotSupported

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 ValidityVTable<ArrowVTable> for ArrowVTable

fn all_invalid(array: &ArrowArray) -> VortexResult<bool>

fn validity_mask(array: &ArrowArray) -> VortexResult<Mask>

fn valid_count(array: &V::Array) -> VortexResult<usize>

Returns the number of valid elements in the array.

fn invalid_count(array: &V::Array) -> VortexResult<usize>

Returns the number of invalid elements in the array.

impl VisitorVTable<ArrowVTable> for ArrowVTable

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

Visit the buffers of the array.

fn visit_children(_array: &ArrowArray, _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.
