Expand description

Fast access by index.

Required Methods§

source

unsafe fn take_unchecked<I, INulls>( &self, indices: TakeIdx<'_, I, INulls> ) -> Selfwhere Self: Sized, I: TakeIterator, INulls: TakeIteratorNulls,

Take values from ChunkedArray by index.

Safety

Doesn’t do any bound checking.

source

fn take<I, INulls>(&self, indices: TakeIdx<'_, I, INulls>) -> PolarsResult<Self>where Self: Sized, I: TakeIterator, INulls: TakeIteratorNulls,

Take values from ChunkedArray by index. Note that the iterator will be cloned, so prefer an iterator that takes the owned memory by reference.
