Trait polars::chunked_array::ops::ChunkTake

pub trait ChunkTake {
    unsafe fn take_unchecked<I, INulls>(
        &self, 
        indices: TakeIdx<'_, I, INulls>
    ) -> Self
    where
        I: TakeIterator,
        INulls: TakeIteratorNulls;
    fn take<I, INulls>(
        &self, 
        indices: TakeIdx<'_, I, INulls>
    ) -> Result<Self, PolarsError>
    where
        I: TakeIterator,
        INulls: TakeIteratorNulls;
}

Fast access by index.

Required methods

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

Take values from ChunkedArray by index.

Safety

Doesn’t do any bound checking.

fn take<I, INulls>(
    &self,
    indices: TakeIdx<'_, I, INulls>
) -> Result<Self, PolarsError> where
    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.
