Struct arrow2::array::growable::GrowableBinary

pub struct GrowableBinary<'a, O: Offset> { /* private fields */ }

Concrete Growable for the BinaryArray.

Implementations

impl<'a, O: Offset> GrowableBinary<'a, O>

pub fn new(
    arrays: Vec<&'a BinaryArray<O>>,
    use_validity: bool,
    capacity: usize
) -> Self

Creates a new GrowableBinary bound to arrays with a pre-allocated capacity.

Panics

If arrays is empty.

Trait Implementations

impl<'a, O: Offset> From<GrowableBinary<'a, O>> for BinaryArray<O>

fn from(val: GrowableBinary<'a, O>) -> Self

Converts to this type from the input type.

impl<'a, O: Offset> Growable<'a> for GrowableBinary<'a, O>

fn extend(&mut self, index: usize, start: 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
