Trait Implementations

impl ArrayEncodingExt for SparseEncoding

type D = Sparse

fn with_dyn<R, F>(array: &ArrayData, f: F) -> R

where F: for<'b> FnMut(&'b (dyn ArrayTrait + 'b)) -> R,

impl ComputeVTable for SparseEncoding

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

Filter an array with a given mask.

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

Single item indexing on Vortex arrays.

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

Perform a search over an ordered array.

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, _lhs: &ArrayData, _rhs: &ArrayData, ) -> 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 subtract_scalar_fn(&self) -> Option<&dyn SubtractScalarFn<ArrayData>>

Broadcast subtraction of scalar from Vortex array.

impl Debug for SparseEncoding

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

Formats the value using the given formatter.

impl Encoding for SparseEncoding

type Array = SparseArray

type Metadata = SparseMetadata

impl EncodingVTable for SparseEncoding

fn id(&self) -> EncodingId

fn as_any(&self) -> &dyn Any

fn with_dyn( &self, array: &ArrayData, f: &mut dyn for<'b> FnMut(&'b (dyn ArrayTrait + 'b)) -> VortexResult<()>, ) -> VortexResult<()>

Unwrap the provided array into an implementation of ArrayTrait

impl FilterFn<SparseArray> for SparseEncoding

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

Filter an array by the provided predicate.

impl ScalarAtFn<SparseArray> for SparseEncoding

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

impl SearchSortedFn<SparseArray> for SparseEncoding

fn search_sorted( &self, array: &SparseArray, value: &Scalar, side: SearchSortedSide, ) -> VortexResult<SearchResult>

fn search_sorted_usize( &self, array: &Array, value: usize, side: SearchSortedSide, ) -> VortexResult<SearchResult>

impl SliceFn<SparseArray> for SparseEncoding

fn slice( &self, array: &SparseArray, 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.
