Struct datafusion::types::Array

pub struct Array { /* fields omitted */ }

Methods

impl Array

pub fn new(len: usize, data: ArrayData) -> Self

Create a new array where there are no null values

pub fn with_nulls(     len: usize,     data: ArrayData,     null_count: usize,     bitmap: Bitmap ) -> Self

Create a new array where there are no null values

pub fn data(&self) -> &ArrayData

Get a reference to the array data

pub fn len(&self) -> usize

number of elements in the array

pub fn null_count(&self) -> usize

number of null elements in the array

pub fn validity_bitmap(&self) -> &Option<Bitmap>

If null_count is greater than zero then the validity_bitmap will be Some(Bitmap)
