Trait polars_core::chunked_array::iterator::IntoNoNullIterator

pub trait IntoNoNullIterator {
    type Item;
    type IntoIter: Iterator<Item = Self::Item>;
    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.
