Trait Implementations

impl ComputeVTable for ListEncoding

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 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.

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

Binary operator implementation for arrays against other arrays.

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

Filter an array with a given mask.

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

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

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

Perform a SQL LIKE operation on two arrays.

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.

fn subtract_scalar_fn(&self) -> Option<&dyn SubtractScalarFn<ArrayData>>

Broadcast subtraction of scalar from Vortex 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.

impl Debug for ListEncoding

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

Formats the value using the given formatter.

impl Encoding for ListEncoding

const ID: EncodingId = _

type Array = ListArray

type Metadata = ListMetadata

impl EncodingVTable for ListEncoding

fn id(&self) -> EncodingId

fn as_any(&self) -> &dyn Any

impl ScalarAtFn<ListArray> for ListEncoding

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

impl SliceFn<ListArray> for ListEncoding

fn slice( &self, array: &ListArray, 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<ListArray> for ListEncoding

fn compute_statistics( &self, _array: &ListArray, _stat: Stat, ) -> VortexResult<StatsSet>

Compute the requested statistic. Can return additional stats.
