Trait Implementations

impl Array for StructArray

type Builder = StructArrayBuilder

Corresponding builder of this array, which is reciprocal to Array.

type OwnedItem = StructValue

Owned type of item in array, which is reciprocal to Self::RefItem.

type RefItem<'a> = StructRef<'a>

A reference to item in array, as well as return type of value_at, which is reciprocal to Self::OwnedItem.

unsafe fn raw_value_at_unchecked(&self, idx: usize) -> StructRef<'_>

Retrieve a reference to value regardless of whether it is null without checking the index boundary.

fn len(&self) -> usize

Number of items of array.

fn to_protobuf(&self) -> PbArray

Serialize to protobuf

fn null_bitmap(&self) -> &Bitmap

Get the null Bitmap from Array.

fn into_null_bitmap(self) -> Bitmap

Get the owned null Bitmap from Array.

fn set_bitmap(&mut self, bitmap: Bitmap)

fn data_type(&self) -> DataType

fn value_at(&self, idx: usize) -> Option<Self::RefItem<'_>>

Retrieve a reference to value.

unsafe fn value_at_unchecked(&self, idx: usize) -> Option<Self::RefItem<'_>>

Safety

fn iter(&self) -> ArrayIterator<'_, Self>

Get iterator of current array.

fn raw_iter(&self) -> impl ExactSizeIterator<Item = Self::RefItem<'_>>

Get raw iterator of current array.

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

Check if an element is null or not.

unsafe fn is_null_unchecked(&self, idx: usize) -> bool

Safety

fn hash_at<H: Hasher>(&self, idx: usize, state: &mut H)

Feed the value at idx into the given Hasher.

fn hash_vec<H: Hasher>(&self, hashers: &mut [H], vis: &Bitmap)

fn is_empty(&self) -> bool

fn create_builder(&self, capacity: usize) -> Self::Builder

fn into_ref(self) -> ArrayRef

Converts the array into an ArrayRef.

impl Clone for StructArray

fn clone(&self) -> StructArray

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StructArray

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

Formats the value using the given formatter.

impl EstimateSize for StructArray

fn estimated_heap_size(&self) -> usize

The estimated heap size of the current struct in bytes.

fn estimated_size(&self) -> usize

where Self: Sized,

The estimated total size of the current struct in bytes, including the estimated_heap_size and the size of Self.

impl<'a> From<&'a ArrayImpl> for &'a StructArray

fn from(array: &'a ArrayImpl) -> Self

Converts to this type from the input type.

impl<'a> From<&'a StructArray> for DataChunk

fn from(array: &'a StructArray) -> Self

Converts to this type from the input type.

impl From<ArrayImpl> for StructArray

fn from(array: ArrayImpl) -> Self

Converts to this type from the input type.

impl From<DataChunk> for StructArray

fn from(chunk: DataChunk) -> Self

Converts to this type from the input type.

impl From<StructArray> for ArrayImpl

fn from(arr: StructArray) -> Self

Converts to this type from the input type.

impl PartialEq for StructArray

fn eq(&self, other: &StructArray) -> 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.
