impl AsRef<ArrayData> for ChunkedArray

fn as_ref(&self) -> &ArrayData

Converts this type into a shared reference of the (usually inferred) input type.

impl BoolArrayTrait for ChunkedArray

fn invert(&self) -> VortexResult<ArrayData>

Return a new inverted version of this array.

impl CastFn<ChunkedArray> for ChunkedEncoding

fn cast(&self, array: &ChunkedArray, dtype: &DType) -> VortexResult<ArrayData>

impl Clone for ChunkedArray

fn clone(&self) -> ChunkedArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompareFn<ChunkedArray> for ChunkedEncoding

fn compare( &self, lhs: &ChunkedArray, rhs: &ArrayData, operator: Operator, ) -> VortexResult<Option<ArrayData>>

Compares two arrays and returns a new boolean array with the result of the comparison. Or, returns None if comparison is not supported for these arrays.

impl Debug for ChunkedArray

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

Formats the value using the given formatter.

impl ExtensionArrayTrait for ChunkedArray

fn storage_data(&self) -> ArrayData

Returns the underlying ArrayData, without the ExtDType.
