Struct vortex_array::array::NullArray

pub struct NullArray(/* private fields */);

Implementations

impl NullArray

pub fn maybe_from(data: impl AsRef<ArrayData>) -> Option<Self>

Optionally downcast an ArrayData instance to a specific encoding.

Preferred in cases where a backtrace isn’t needed, like when trying multiple encoding to go down different code paths.

impl NullArray

pub fn new(len: usize) -> Self

Trait Implementations

impl AsRef<ArrayData> for NullArray

fn as_ref(&self) -> &ArrayData

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

impl BinaryNumericFn<NullArray> for NullEncoding

fn binary_numeric( &self, array: &NullArray, _rhs: &ArrayData, _op: BinaryNumericOperator, ) -> VortexResult<Option<ArrayData>>

impl Clone for NullArray

fn clone(&self) -> NullArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NullArray

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

Formats the value using the given formatter.

impl IntoArrayData for NullArray

fn into_array(self) -> ArrayData

impl IntoCanonical for NullArray

fn into_canonical(self) -> VortexResult<Canonical>

fn into_arrow(self) -> VortexResult<ArrayRef>

where Self: Sized,

impl ScalarAtFn<NullArray> for NullEncoding

fn scalar_at(&self, _array: &NullArray, _index: usize) -> VortexResult<Scalar>

impl SliceFn<NullArray> for NullEncoding

fn slice( &self, _array: &NullArray, 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<NullArray> for NullEncoding

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

Compute the requested statistic. Can return additional stats.

impl TakeFn<NullArray> for NullEncoding

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

Create a new array by taking the values from the array at the given indices.

unsafe fn take_unchecked( &self, _array: &NullArray, indices: &ArrayData, ) -> VortexResult<ArrayData>

Create a new array by taking the values from the array at the given indices.

impl<'a> TryFrom<&'a ArrayData> for &'a NullArray

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 NullArray

type Error = VortexError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl ValidityVTable<NullArray> for NullEncoding

fn is_valid(&self, _array: &NullArray, _idx: usize) -> bool

fn logical_validity(&self, array: &NullArray) -> LogicalValidity
