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

Formats the value using the given formatter.

impl Encoding for ChunkedEncoding

type Array = ChunkedArray

type Metadata = EmptyMetadata

fn vtable(&'static self) -> VTableRef

where Self: Sized,

impl EncodingVTable for ChunkedEncoding

fn id(&self) -> EncodingId

Return the ID for this encoding implementation.

fn decode( &self, parts: &ArrayParts, ctx: &ArrayContext, dtype: DType, _len: usize, ) -> VortexResult<ArrayRef>

fn encode( &self, input: &Canonical, _like: Option<&dyn Array>, ) -> VortexResult<Option<ArrayRef>>

Encode the canonical array into this encoding implementation.

impl FillNullFn<&ChunkedArray> for ChunkedEncoding

fn fill_null( &self, array: &ChunkedArray, fill_value: Scalar, ) -> VortexResult<ArrayRef>

impl FilterKernel for ChunkedEncoding

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

Filter an array by the provided predicate.

impl InvertKernel for ChunkedEncoding

fn invert(&self, array: &ChunkedArray) -> VortexResult<ArrayRef>

Logically invert a boolean array. Converts true -> false, false -> true, null -> null.

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

Preconditions
