Struct arrow::array::BinaryArray

pub struct BinaryArray { /* fields omitted */ }

A type of ListArray whose elements are binaries.

Methods

impl BinaryArray

pub fn value(&self, i: usize) -> &[u8]

Returns the element at index i as a byte slice.

pub fn value_offset(&self, i: usize) -> i32

Returns the offset for the element at index i.

Note this doesn't do any bound checking, for performance reason.

pub fn value_length(&self, i: usize) -> i32

Returns the length for the element at index i.

Note this doesn't do any bound checking, for performance reason.

pub fn value_offsets(&self) -> Buffer

Returns a clone of the value offset buffer

pub fn value_data(&self) -> Buffer

Returns a clone of the value data buffer

Trait Implementations

impl Array for BinaryArray

fn as_any(&self) -> &dyn Any

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

fn data(&self) -> ArrayDataRef

Returns a reference-counted pointer to the data of this array

fn data_ref(&self) -> &ArrayDataRef

Returns a borrowed & reference-counted pointer to the data of this array

fn data_type(&self) -> &DataType

Returns a reference to the data type 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 offset(&self) -> usize

Returns the offset of this array

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

Returns whether the element at index i is null

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

Returns whether the element at index i is not null

fn null_count(&self) -> usize

Returns the total number of nulls in this array

impl ArrayEqual for BinaryArray

fn equals(&self, other: &dyn Array) -> bool

Returns true if this array is equal to the other array

fn range_equals(
    &self,
    other: &dyn Array,
    start_idx: usize,
    end_idx: usize,
    other_start_idx: usize
) -> bool

Returns true if the range [start_idx, end_idx) is equal to [other_start_idx, other_start_idx + end_idx - start_idx) in the other array

impl Debug for BinaryArray

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

Formats the value using the given formatter.

impl From<Arc<ArrayData>> for BinaryArray

fn from(data: ArrayDataRef) -> Self

Performs the conversion.
