[GitHub] [arrow-rs] jhorstmann opened a new issue #1429: DictionaryArray::try_new ignores validity bitmap of the keys

jhorstmann opened a new issue #1429:
URL: https://github.com/apache/arrow-rs/issues/1429


   **Describe the bug**
   
   The `try_new` method seems to ignore the validity bitmap of the key array:
   
   
   **To Reproduce**
   
   ```rust
   let values: StringArray = [Some("foo"), Some("bar"), Some("baz")]
       .into_iter()
       .collect();
   let keys: Int32Array = [Some(0), Some(2), None, Some(1)].into_iter().collect();
   
   let array = DictionaryArray::<Int32Type>::try_new(&keys, &values).unwrap();
   
   assert!(array.keys.is_valid(0));
   assert!(array.keys.is_valid(1));
   assert!(array.keys.is_null(2));
   assert!(array.keys.is_valid(3));
   ```
