Struct VectorArray 

pub struct VectorArray {
    bitmap: Bitmap,
    offsets: Vec<u32>,
    inner: Vec<VectorItemType>,

Trait Implementations

impl Array for VectorArray

type Builder = VectorArrayBuilder

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

type OwnedItem = VectorInner<Box<[OrderedFloat<f32>]>>

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

type RefItem<'a> = VectorInner<&'a [OrderedFloat<f32>]>

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) -> Self::RefItem<'_>

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<'_>>

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)

impl EstimateSize for VectorArray

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.
