Struct GrowableBoolean

pub struct GrowableBoolean<'a> { /* private fields */ }

Concrete Growable for the BooleanArray.

Implementations

impl<'a> GrowableBoolean<'a>

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

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

Panics

If arrays is empty.

Trait Implementations

impl<'a> From<GrowableBoolean<'a>> for BooleanArray

fn from(val: GrowableBoolean<'a>) -> Self

Converts to this type from the input type.

impl<'a> Growable<'a> for GrowableBoolean<'a>

unsafe 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 len(&self) -> usize

The current length of the Growable.

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

unsafe fn extend_copies( &mut self, index: usize, start: usize, len: usize, copies: usize, )

Same as extend, except it repeats the extension copies times.
