Struct re_sdk::external::arrow2::array::growable::GrowableList

pub struct GrowableList<'a, O>
where
    O: Offset,
{
    arrays: Vec<&'a ListArray<O>>,
    validity: MutableBitmap,
    values: Box<dyn Growable<'a> + 'a>,
    offsets: Offsets<O>,
    extend_null_bits: Vec<Box<dyn Fn(&mut MutableBitmap, usize, usize) + 'a>>,
}

Concrete Growable for the ListArray.

Fields

arrays: Vec<&'a ListArray<O>>

validity: MutableBitmap

values: Box<dyn Growable<'a> + 'a>

offsets: Offsets<O>

extend_null_bits: Vec<Box<dyn Fn(&mut MutableBitmap, usize, usize) + 'a>>

Implementations

impl<'a, O> GrowableList<'a, O>

where O: Offset,

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

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

Panics

If arrays is empty.

Trait Implementations

impl<'a, O> From<GrowableList<'a, O>> for ListArray<O>

where O: Offset,

fn from(val: GrowableList<'a, O>) -> ListArray<O>

Converts to this type from the input type.

impl<'a, O> Growable<'a> for GrowableList<'a, O>

where O: Offset,

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
