impl AsRef<ArrayData> for DictArray

fn as_ref(&self) -> &ArrayData

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

impl BoolArrayTrait for DictArray

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

Return a new inverted version of this array.

impl Clone for DictArray

fn clone(&self) -> DictArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompareFn<DictArray> for DictEncoding

fn compare( &self, lhs: &DictArray, 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 DictArray

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

Formats the value using the given formatter.

impl FilterFn<DictArray> for DictEncoding

fn filter(&self, array: &DictArray, mask: FilterMask) -> VortexResult<ArrayData>

Filter an array by the provided predicate.

impl IntoArrayData for DictArray

fn into_array(self) -> ArrayData

impl IntoCanonical for DictArray

fn into_canonical(self) -> VortexResult<Canonical>

impl PrimitiveArrayTrait for DictArray

fn ptype(&self) -> PType

fn scalar_at(&self, array: &DictArray, index: usize) -> VortexResult<Scalar>

impl SliceFn<DictArray> for DictEncoding

fn slice( &self, array: &DictArray, start: usize, stop: usize, ) -> VortexResult<ArrayData>

Return a zero-copy slice of an array, between start (inclusive) and end (exclusive). If start >= stop, returns an empty array of the same type as self. Assumes that start or stop are out of bounds, may panic otherwise.

fn compute_statistics( &self, array: &DictArray, stat: Stat, ) -> VortexResult<StatsSet>

Compute the requested statistic. Can return additional stats.

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(data: &'a ArrayData) -> VortexResult<Self>

Performs the conversion.

impl TryFrom<ArrayData> for DictArray

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(data: ArrayData) -> VortexResult<Self>

Performs the conversion.
