Struct arrow2::array::growable::GrowableNull

pub struct GrowableNull { /* private fields */ }

Concrete Growable for the NullArray.

Implementations

impl GrowableNull

pub fn new(data_type: DataType) -> Self

Creates a new GrowableNull.

Trait Implementations

impl Default for GrowableNull

fn default() -> Self

Returns the “default value” for a type.

impl From<GrowableNull> for NullArray

fn from(val: GrowableNull) -> Self

Performs the conversion.

impl<'a> Growable<'a> for GrowableNull

fn extend(&mut self, _: usize, _: usize, len: usize)

Extends this Growable with elements from the bounded Array at index index from a slice starting at start and length len.

fn extend_validity(&mut self, additional: usize)

Extends this Growable with null elements, disregarding the bound arrays

fn as_arc(&mut self) -> Arc<dyn Array>

Converts this Growable to an Arc<dyn Array>, thereby finishing the mutation. Self will be empty after such operation.

fn as_box(&mut self) -> Box<dyn Array>

Converts this Growable to an Box<dyn Array>, thereby finishing the mutation. Self will be empty after such operation
