Trait Implementations

impl<T: ArrowPrimitiveType> Array for ParallelPrimitiveArray<T>

fn as_any(&self) -> &dyn Any

Returns the array as Any so that it can be downcasted to a specific implementation.

fn to_data(&self) -> ArrayData

Returns the underlying data of this array

fn into_data(self) -> ArrayData

Returns the underlying data of this array

fn data_type(&self) -> &DataType

Returns a reference to the DataType of this array.

fn slice(&self, offset: usize, length: usize) -> ArrayRef

Returns a zero-copy slice of this array with the indicated offset and length.

fn len(&self) -> usize

Returns the length (i.e., number of elements) of this array.

fn is_empty(&self) -> bool

Returns whether this array is empty.

fn offset(&self) -> usize

Returns the offset into the underlying data used by this array(-slice). Note that the underlying data can be shared by many arrays. This defaults to 0.

fn nulls(&self) -> Option<&NullBuffer>

Returns the null buffer of this array if any.

fn get_buffer_memory_size(&self) -> usize

Returns the total number of bytes of memory pointed to by this array. The buffers store bytes in the Arrow memory format, and include the data as well as the validity map. Note that this does not always correspond to the exact memory usage of an array, since multiple arrays can share the same buffers or slices thereof.

fn get_array_memory_size(&self) -> usize

Returns the total number of bytes of memory occupied physically by this array. This value will always be greater than returned by get_buffer_memory_size() and includes the overhead of the data structures that contain the pointers to the various buffers.

fn logical_nulls(&self) -> Option<NullBuffer>

Returns a potentially computed NullBuffer that represents the logical null values of this array, if any.

fn is_null(&self, index: usize) -> bool

Returns whether the element at index is null according to Array::nulls

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

Returns whether the element at index is not null, the opposite of Self::is_null.

fn null_count(&self) -> usize

Returns the total number of physical null values in this array.

fn is_nullable(&self) -> bool

Returns false if the array is guaranteed to not contain any logical nulls

impl<T: Clone + ArrowPrimitiveType> Clone for ParallelPrimitiveArray<T>

fn clone(&self) -> ParallelPrimitiveArray<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ArrowPrimitiveType> Debug for ParallelPrimitiveArray<T>

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

Formats the value using the given formatter.

impl<T: ArrowPrimitiveType> From<PrimitiveArray<T>> for ParallelPrimitiveArray<T>

fn from(array: PrimitiveArray<T>) -> Self

Converts to this type from the input type.

impl<T: ArrowPrimitiveType, Ptr: Into<NativeAdapter<T>> + Send> FromParallelIterator<Ptr> for ParallelPrimitiveArray<T>

fn from_par_iter<I>(par_iter: I) -> Self

where I: IntoParallelIterator<Item = Ptr>,

Creates an instance of the collection from the parallel iterator par_iter.

impl<T: ArrowPrimitiveType> IntoParallelIterator for ParallelPrimitiveArray<T>

type Item = Option<<T as ArrowPrimitiveType>::Native>

The type of item that the parallel iterator will produce.

type Iter = ParallelPrimitiveArrayIter<T>

The parallel iterator type that will be created.

fn into_par_iter(self) -> Self::Iter

Converts self into a parallel iterator.
