pub struct GrowableNull { /* private fields */ }

Expand description

Concrete Growable for the NullArray.

Implementations

source

impl GrowableNull

source

pub fn new(data_type: DataType) -> GrowableNull

Creates a new GrowableNull.

Trait Implementations

source

impl Default for GrowableNull

source

fn default() -> GrowableNull

Returns the “default value” for a type. Read more

source

impl From<GrowableNull> for NullArray

source

fn from(val: GrowableNull) -> NullArray

Performs the conversion.

source

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

source

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. Read more

source

fn extend_validity(&mut self, additional: usize)

Extends this Growable with null elements, disregarding the bound arrays

source

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

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

source

fn as_box(&mut self) -> Box<dyn Array + 'static, Global>

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