Trait Implementations

impl BinaryNumericFn<DictArray> for DictEncoding

fn binary_numeric( &self, array: &DictArray, rhs: &ArrayData, op: BinaryNumericOperator, ) -> VortexResult<Option<ArrayData>>

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 ComputeVTable for DictEncoding

fn binary_numeric_fn(&self) -> Option<&dyn BinaryNumericFn<ArrayData>>

Implementation of binary numeric operations.

fn compare_fn(&self) -> Option<&dyn CompareFn<ArrayData>>

Binary operator implementation for arrays against other arrays.

fn filter_fn(&self) -> Option<&dyn FilterFn<ArrayData>>

Filter an array with a given mask.

fn like_fn(&self) -> Option<&dyn LikeFn<ArrayData>>

Perform a SQL LIKE operation on two arrays.

fn scalar_at_fn(&self) -> Option<&dyn ScalarAtFn<ArrayData>>

Single item indexing on Vortex arrays.

fn slice_fn(&self) -> Option<&dyn SliceFn<ArrayData>>

Perform zero-copy slicing of an array.

fn take_fn(&self) -> Option<&dyn TakeFn<ArrayData>>

Take a set of indices from an array. This often forces allocations and decoding of the receiver.

fn binary_boolean_fn(&self) -> Option<&dyn BinaryBooleanFn<ArrayData>>

Implementation of binary boolean logic operations.

fn cast_fn(&self) -> Option<&dyn CastFn<ArrayData>>

Implemented for arrays that can be casted to different types. Implemented for arrays that can be casted to different types.

fn fill_forward_fn(&self) -> Option<&dyn FillForwardFn<ArrayData>>

Array function that returns new arrays a non-null value is repeated across runs of nulls.

fn fill_null_fn(&self) -> Option<&dyn FillNullFn<ArrayData>>

Fill null values with given desired value. Resulting array is NonNullable

fn invert_fn(&self) -> Option<&dyn InvertFn<ArrayData>>

Invert a boolean array. Converts true -> false, false -> true, null -> null.

fn search_sorted_fn(&self) -> Option<&dyn SearchSortedFn<ArrayData>>

Perform a search over an ordered array.

fn search_sorted_usize_fn(&self) -> Option<&dyn SearchSortedUsizeFn<ArrayData>>

Perform a search over an ordered array.

impl Debug for DictEncoding

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

Formats the value using the given formatter.

impl Encoding for DictEncoding

const ID: EncodingId

type Array = DictArray

type Metadata = SerdeMetadata<DictMetadata>

impl EncodingVTable for DictEncoding

fn id(&self) -> EncodingId

impl FilterFn<DictArray> for DictEncoding

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

Filter an array by the provided predicate.

impl LikeFn<DictArray> for DictEncoding

fn like( &self, array: DictArray, pattern: &ArrayData, options: LikeOptions, ) -> VortexResult<Option<ArrayData>>

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.

impl StatisticsVTable<DictArray> for DictEncoding

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

Compute the requested statistic. Can return additional stats.

impl TakeFn<DictArray> for DictEncoding

fn take( &self, array: &DictArray, indices: &ArrayData, ) -> VortexResult<ArrayData>
