Struct VariableShapeTensorBatchView 

pub struct VariableShapeTensorBatchView<'a, T>
where
    T: ArrowPrimitiveType,
    T::Native: NdarrowElement,
{ /* private fields */ }

Column-level zero-copy view over arrow.variable_shape_tensor storage.

Implementations

impl<'a, T> VariableShapeTensorBatchView<'a, T>

where T: ArrowPrimitiveType, T::Native: NdarrowElement,

pub fn len(&self) -> usize

Returns the number of batch rows.

pub fn is_empty(&self) -> bool

Returns whether the batch is empty.

pub fn nulls(&self) -> Option<&'a NullBuffer>

Returns the optional outer-row validity bitmap.

pub fn dimensions(&self) -> usize

Returns the tensor rank encoded for each row.

pub fn uniform_shape(&self) -> Option<&[Option<i32>]>

Returns the optional uniform-shape metadata.

pub fn data_offsets(&self) -> &[i32]

Returns the raw Arrow list offsets for packed row data.

pub fn values(&self) -> &'a [T::Native]

Returns the packed primitive values buffer for the whole batch.

pub fn shape_values(&self) -> &[i32]

Returns the packed shape buffer for the whole batch.

pub fn row( &self, index: usize, ) -> Result<VariableShapeTensorRowView<'a, T::Native>, NdarrowError>

Returns a validated row view at index.

Errors

Returns an error if index is out of bounds or the row metadata is structurally invalid.

pub fn iter(&self) -> VariableShapeTensorIter<'a, T>

Returns the per-row iterator convenience view for this batch.

Trait Implementations

impl<T> Clone for VariableShapeTensorBatchView<'_, T>

where T: ArrowPrimitiveType, T::Native: NdarrowElement,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T> IntoIterator for &'a VariableShapeTensorBatchView<'a, T>

where T: ArrowPrimitiveType, T::Native: NdarrowElement,

type IntoIter = VariableShapeTensorIter<'a, T>

Which kind of iterator are we turning this into?

type Item = Result<(usize, ArrayBase<ViewRepr<&'a <T as ArrowPrimitiveType>::Native>, Dim<IxDynImpl>>), NdarrowError>

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
