Trait Implementations

impl ArrayBuilder for StructArrayBuilder

type ArrayType = StructArray

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

fn new(_capacity: usize) -> Self

Create a new builder with capacity. TODO: remove this function from the trait. Let it be methods of each concrete builders.

fn with_type(capacity: usize, ty: DataType) -> Self

Panics

fn append_n(&mut self, n: usize, value: Option<StructRef<'_>>)

Append a value multiple times.

fn append_array(&mut self, other: &StructArray)

Append an array to builder.

fn pop(&mut self) -> Option<()>

Pop an element from the builder.

fn len(&self) -> usize

Return the number of elements in the builder.

fn finish(self) -> StructArray

Finish build and return a new array.

fn append(&mut self, value: Option<<Self::ArrayType as Array>::RefItem<'_>>)

Append a value to builder.

fn append_owned(&mut self, value: Option<<Self::ArrayType as Array>::OwnedItem>)

Append an owned value to builder.

fn append_null(&mut self)

fn append_array_element(&mut self, other: &Self::ArrayType, idx: usize)

Append an element in another array into builder.

fn is_empty(&self) -> bool

Return true if the array has a length of 0.

impl Clone for StructArrayBuilder

fn clone(&self) -> StructArrayBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructArrayBuilder

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

Formats the value using the given formatter.

impl EstimateSize for StructArrayBuilder

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 From<StructArrayBuilder> for ArrayBuilderImpl

fn from(builder: StructArrayBuilder) -> Self

Converts to this type from the input type.
