Trait Implementations

impl ArrayEncodingExt for ZigZagEncoding

type D = ZigZag

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

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

impl ComputeVTable for ZigZagEncoding

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

Filter an array with a given mask.

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

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

Formats the value using the given formatter.

impl Encoding for ZigZagEncoding

type Array = ZigZagArray

type Metadata = ZigZagMetadata

impl EncodingVTable for ZigZagEncoding

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 ScalarAtFn<ZigZagArray> for ZigZagEncoding

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

impl SliceFn<ZigZagArray> for ZigZagEncoding

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