Trait polars::prelude::IntoNoNullIterator

pub trait IntoNoNullIterator {
    type Item;
    type IntoIter: Iterator;
    pub fn into_no_null_iter(self) -> Self::IntoIter;
}

Trait for ChunkedArrays that don't have null values. The result is the most efficient implementation Iterator, according to the number of chunks.

Implementors

impl<'a> IntoNoNullIterator for &'a ChunkedArray<BooleanType>

type Item = bool

type IntoIter = Box<dyn PolarsIterator<Item = <&'a ChunkedArray<BooleanType> as IntoNoNullIterator>::Item> + 'a, Global>

pub fn into_no_null_iter(
    self
) -> <&'a ChunkedArray<BooleanType> as IntoNoNullIterator>::IntoIter

Decides which iterator fits best the current no null chunked array. The decision are based on the number of chunks.
