Struct arrow::list::List

pub struct List<T> where
    T: ArrowPrimitiveType,  { /* fields omitted */ }

List is a nested type in which each array slot contains a variable-size sequence of values of the same type T

Methods

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

pub fn from_raw_parts(data: Buffer<T>, offsets: Buffer<i32>) -> Self

Create a List from raw parts

pub fn len(&self) -> usize

Get the length of the List (number of array slots)

pub fn data(&self) -> &Buffer<T>

Get a reference to the raw data in the list

pub fn offsets(&self) -> &Buffer<i32>

Get a reference to the offsets in the list

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

Get the contents of a single array slot
