Struct arrow::array::FixedSizeBinaryArray

pub struct FixedSizeBinaryArray { /* fields omitted */ }

A type of FixedSizeListArray whose elements are binaries.

Implementations

impl FixedSizeBinaryArray

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) -> i32

Returns the length for an element.

All elements have the same length as the array is a fixed size.

pub fn value_data(&self) -> Buffer

Returns a clone of the value data buffer

Trait Implementations

impl Array for FixedSizeBinaryArray

fn as_any(&self) -> &dyn Any

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

fn data(&self) -> ArrayDataRef

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

fn data_ref(&self) -> &ArrayDataRef

Returns a borrowed & reference-counted pointer to 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 is_null(&self, index: usize) -> bool

Returns whether the element at index is null. When using this function on a slice, the index is relative to the slice.

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

Returns whether the element at index is not null. When using this function on a slice, the index is relative to the slice.

fn null_count(&self) -> usize

Returns the total number of null values in this array.

impl ArrayEqual for FixedSizeBinaryArray

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 FixedSizeBinaryArray

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

Formats the value using the given formatter.

impl From<Arc<ArrayData>> for FixedSizeBinaryArray

fn from(data: ArrayDataRef) -> Self

Performs the conversion.

impl From<FixedSizeListArray> for FixedSizeBinaryArray

Creates a FixedSizeBinaryArray from FixedSizeList<u8> array

fn from(v: FixedSizeListArray) -> Self

Performs the conversion.

impl JsonEqual for FixedSizeBinaryArray

fn equals_json(&self, json: &[&Value]) -> bool

Checks whether arrow array equals to json array.

fn equals_json_values(&self, json: &[Value]) -> bool

Checks whether arrow array equals to json array.

impl ListArrayOps for FixedSizeBinaryArray

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

impl PartialEq<FixedSizeBinaryArray> for FixedSizeBinaryArray

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialEq<FixedSizeBinaryArray> for Value

fn eq(&self, arrow: &FixedSizeBinaryArray) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialEq<Value> for FixedSizeBinaryArray

fn eq(&self, json: &Value) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
