Expand description

Fast access by index.

Required methods

unsafe fn take_unchecked<I, INulls>(
    &self,
    indices: TakeIdx<'_, I, INulls>
) -> Self where
    Self: Sized,
    I: Iterator<Item = usize>,
    INulls: Iterator<Item = Option<usize>>, [src]

Take values from ChunkedArray by index.

Safety

Doesn’t do any bound checking.

fn take<I, INulls>(&self, indices: TakeIdx<'_, I, INulls>) -> Self where
    Self: Sized,
    I: Iterator<Item = usize>,
    INulls: Iterator<Item = Option<usize>>, [src]

Take values from ChunkedArray by index.
