Methods

impl<T> ListArray<T> where
    T: ArrowPrimitiveType, 

pub fn len(&self) -> usize

pub fn null_count(&self) -> usize

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

pub fn get(&self, i: usize) -> &[T]

pub fn list(&self) -> &List<T>

Trait Implementations

impl<T> From<List<T>> for ListArray<T> where
    T: ArrowPrimitiveType, 

Create a ListArray from a List without null values

fn from(list: List<T>) -> Self

Performs the conversion.

impl From<Vec<&'static str>> for ListArray<u8>

Create ListArray from Vec<&'static str>

fn from(v: Vec<&'static str>) -> Self

Performs the conversion.

impl From<Vec<String>> for ListArray<u8>

Create ListArray from Vec

fn from(v: Vec<String>) -> Self

Performs the conversion.

impl<T> Array for ListArray<T> where
    T: ArrowPrimitiveType, 

fn len(&self) -> usize

Returns the length of the array (number of items in the array)

fn null_count(&self) -> usize

Returns the number of null values in the array

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

Optional validity bitmap (can be None if there are no null values)

fn as_any(&self) -> &Any

Return the array as Any so that it can be downcast to a specific implementation
