[jira] [Resolved] (ARROW-10298) [Rust] Incorrect offset handling in iterator over dictionary keys

     [ https://issues.apache.org/jira/browse/ARROW-10298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jörn Horstmann resolved ARROW-10298.
------------------------------------
    Fix Version/s: 3.0.0
       Resolution: Fixed

This was fixed some time ago, DictionaryArray no longer has a separate iterator implementation but instead one can get the keys as a PrimitiveArray and iterate over that.

> The NullableIterator used by DictionaryArray.keys calls ArrayData.is_null without taking the offset of that ArrayData into account. It would probably be better if ArrayData itself handled the offset in that method.
> The iterator implementation could now also be replaced with the PrimitiveIter that was recently added
