Function polars_arrow::kernels::take_agg::take_agg_no_null_primitive_iter_unchecked

pub unsafe fn take_agg_no_null_primitive_iter_unchecked<T: NativeType + ToPrimitive, TOut: NumCast + NativeType, I: IntoIterator<Item = usize>, F: Fn(TOut, TOut) -> TOut>(
    arr: &PrimitiveArray<T>,

) -> TOut

Take kernel for single chunk without nulls and an iterator as index.

Safety

caller must enure iterators indexes are in bounds
