[GitHub] [arrow-rs] viirya opened a new issue, #1962: Incorrect null_count of DictionaryArray

viirya opened a new issue, #1962:
URL: https://github.com/apache/arrow-rs/issues/1962

   **Describe the bug**
   
   `null_count` of `DictionaryArray` calls the default implementation which gets null count of its `data` member. So basically it looks at the null count of keys. If a corresponding value of a key is null, `null_count` cannot get correct null count.
   
   `is_null` and `is_valid` also have same issue.
