Struct vortex_array::array::ExtensionArray

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

Implementations

impl ExtensionArray

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 ExtensionArray

pub fn new(ext_dtype: Arc<ExtDType>, storage: ArrayData) -> Self

pub fn storage(&self) -> ArrayData

pub fn id(&self) -> &ExtID

Trait Implementations

impl AsRef<ArrayData> for ExtensionArray

fn as_ref(&self) -> &ArrayData

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

impl Clone for ExtensionArray

fn clone(&self) -> ExtensionArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompareFn<ExtensionArray> for ExtensionEncoding

fn compare( &self, lhs: &ExtensionArray, rhs: &ArrayData, operator: Operator, ) -> VortexResult<Option<ArrayData>>

Compares two arrays and returns a new boolean array with the result of the comparison. Or, returns None if comparison is not supported for these arrays.

impl Debug for ExtensionArray

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

Formats the value using the given formatter.

impl ExtensionArrayTrait for ExtensionArray

fn storage_data(&self) -> ArrayData

Returns the underlying ArrayData, without the [ExtDType].

fn ext_dtype(&self) -> &Arc<ExtDType>

Returns the extension logical [DType].

impl From<&TemporalArray> for ExtensionArray

fn from(value: &TemporalArray) -> Self

Converts to this type from the input type.

impl From<TemporalArray> for ExtensionArray

fn from(value: TemporalArray) -> Self

Converts to this type from the input type.

impl IntoArrayData for ExtensionArray

fn into_array(self) -> ArrayData

impl IntoCanonical for ExtensionArray

fn into_canonical(self) -> VortexResult<Canonical>

fn into_arrow(self) -> VortexResult<ArrayRef>

where Self: Sized,

impl ScalarAtFn<ExtensionArray> for ExtensionEncoding

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

impl SliceFn<ExtensionArray> for ExtensionEncoding

fn slice( &self, array: &ExtensionArray, 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<ExtensionArray> for ExtensionEncoding

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

Compute the requested statistic. Can return additional stats.

impl TakeFn<ExtensionArray> for ExtensionEncoding

fn take( &self, array: &ExtensionArray, 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: &Array, 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 ExtensionArray

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 ExtensionArray

type Error = VortexError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFrom<ExtensionArray> for TemporalArray

type Error = VortexError

The type returned in the event of a conversion error.

fn try_from(ext: ExtensionArray) -> Result<Self, Self::Error>

Performs the conversion.
