Struct vortex_alp::ALPRDArray

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

Implementations

impl ALPRDArray

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 ALPRDArray

pub fn try_new( dtype: DType, left_parts: ArrayData, left_parts_dict: impl AsRef<[u16]>, right_parts: ArrayData, right_bit_width: u8, left_parts_patches: Option<Patches>, ) -> VortexResult<Self>

pub fn is_f32(&self) -> bool

Returns true if logical type of the array values is f32.

Returns false if the logical type of the array values is f64.

pub fn left_parts(&self) -> ArrayData

The leftmost (most significant) bits of the floating point values stored in the array.

These are bit-packed and dictionary encoded, and cannot directly be interpreted without the metadata of this array.

pub fn right_parts(&self) -> ArrayData

The rightmost (least significant) bits of the floating point values stored in the array.

pub fn left_parts_patches(&self) -> Option<Patches>

Patches of left-most bits.

pub fn left_parts_dict(&self) -> &[u16]

The dictionary that maps the codes in left_parts into bit patterns.

Trait Implementations

impl AsRef<ArrayData> for ALPRDArray

fn as_ref(&self) -> &ArrayData

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

impl Clone for ALPRDArray

fn clone(&self) -> ALPRDArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ALPRDArray

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

Formats the value using the given formatter.

impl FilterFn<ALPRDArray> for ALPRDEncoding

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

Filter an array by the provided predicate.

impl IntoArrayData for ALPRDArray

fn into_array(self) -> ArrayData

impl IntoCanonical for ALPRDArray

fn into_canonical(self) -> VortexResult<Canonical>

fn into_arrow(self) -> Result<Arc<dyn Array>, VortexError>

where Self: Sized,

impl PrimitiveArrayTrait for ALPRDArray

fn ptype(&self) -> PType

The logical primitive type of the array.

impl ScalarAtFn<ALPRDArray> for ALPRDEncoding

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

impl SliceFn<ALPRDArray> for ALPRDEncoding

fn slice( &self, array: &ALPRDArray, 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 TakeFn<ALPRDArray> for ALPRDEncoding

fn take( &self, array: &ALPRDArray, 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, ) -> Result<ArrayData, VortexError>

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

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

impl TryFrom<ArrayData> for ALPRDArray

type Error = VortexError

The type returned in the event of a conversion error.

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