Daniël Heres updated ARROW-10892:
---------------------------------
Description:
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?
