> [Rust] Introduce iterators over elements of arrays
> --------------------------------------------------
>
> Key: ARROW-10892
> URL: https://issues.apache.org/jira/browse/ARROW-10892
> Project: Apache Arrow
> Issue Type: Bug
> Reporter: Daniël Heres
> Priority: Minor
>
> The value functions in the primitive / string / etc arrays are often used to
> get elements at i in a loop. Some of them don't have boundary checks for
> performance reasons, so usage of them is unsafe.
> We should introduce a safe iterator over the elements (T instead of
> Option<T>) that doesn't do boundary checks and can be used to iterate over
> the elements of the array. Maybe values_iter would be a good name?
