Trait polars_arrow::array::iterator::ArrayAccessor

pub unsafe trait ArrayAccessor<'a>: Sealed {
    type Item: 'a;

    // Required methods
    unsafe fn value_unchecked(&'a self, index: usize) -> Self::Item;
    fn len(&self) -> usize;
}

Sealed trait representing access to a value of an array.

Safety

Implementers of this trait guarantee that value_unchecked is safe when called up to len

Required Associated Types

type Item: 'a

Required Methods

unsafe fn value_unchecked(&'a self, index: usize) -> Self::Item

Safety

The index must be in-bounds in the array.

fn len(&self) -> usize
