Struct ListArray

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

Implementations

impl ListArray

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 ListArray

pub fn try_new( elements: ArrayData, offsets: ArrayData, validity: Validity, ) -> VortexResult<Self>

pub fn validity(&self) -> Validity

pub fn offset_at(&self, index: usize) -> usize

pub fn elements_at(&self, index: usize) -> VortexResult<ArrayData>

pub fn offsets(&self) -> ArrayData

pub fn elements(&self) -> ArrayData

Trait Implementations

impl AsRef<ArrayData> for ListArray

fn as_ref(&self) -> &ArrayData

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

impl Clone for ListArray

fn clone(&self) -> ListArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ListArray

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

Formats the value using the given formatter.

impl IntoArrayData for ListArray

fn into_array(self) -> ArrayData

impl IntoCanonical for ListArray

fn into_canonical(self) -> VortexResult<Canonical>

fn into_arrow(self) -> VortexResult<ArrayRef>

where Self: Sized,

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.

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

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 ListArray

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<ListArray> for ListEncoding

fn is_valid(&self, array: &ListArray, index: usize) -> bool

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