Struct BFloat16Array

pub struct BFloat16Array { /* private fields */ }

Implementations

impl BFloat16Array

pub fn from_iter_values(iter: impl IntoIterator<Item = bf16>) -> Self

pub fn iter(&self) -> ArrayIter<&'_ BFloat16Array>

pub fn value(&self, i: usize) -> bf16

pub unsafe fn value_unchecked(&self, i: usize) -> bf16

Safety

Caller must ensure that i < self.len()

pub fn into_inner(self) -> FixedSizeBinaryArray

Trait Implementations

impl Array for BFloat16Array

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

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

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

Returns the null buffer of this array if any.

fn data_type(&self) -> &DataType

Returns a reference to the DataType of this array.

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 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 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 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<'a> ArrayAccessor for &'a BFloat16Array

type Item = bf16

The Arrow type of the element being accessed.

fn value(&self, index: usize) -> Self::Item

Returns the element at index i

unsafe fn value_unchecked(&self, index: usize) -> Self::Item

Returns the element at index i

impl Clone for BFloat16Array

fn clone(&self) -> BFloat16Array

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BFloat16Array

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

Formats the value using the given formatter.

impl FloatArray<BFloat16Type> for BFloat16Array

type FloatType = BFloat16Type

fn as_slice(&self) -> &[bf16]

Returns a reference to the underlying data as a slice.

impl From<Vec<bf16>> for BFloat16Array

fn from(data: Vec<bf16>) -> Self

Converts to this type from the input type.

impl FromIterator<Option<bf16>> for BFloat16Array

fn from_iter<I: IntoIterator<Item = Option<bf16>>>(iter: I) -> Self

Creates a value from an iterator.

impl FromIterator<bf16> for BFloat16Array

fn from_iter<I: IntoIterator<Item = bf16>>(iter: I) -> Self

Creates a value from an iterator.

impl PartialEq for BFloat16Array

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<FixedSizeBinaryArray> for BFloat16Array

type Error = ArrowError

The type returned in the event of a conversion error.

fn try_from(value: FixedSizeBinaryArray) -> Result<Self, Self::Error>

Performs the conversion.
