[jira] [Created] (ARROW-11063) [Rust] Validate null counts when building arrays

Neville Dipale created ARROW-11063:
--------------------------------------

             Summary: [Rust] Validate null counts when building arrays
                 Key: ARROW-11063
                 URL: https://issues.apache.org/jira/browse/ARROW-11063
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Neville Dipale


ArrayDataBuilder allows the user to specify a null count, alternatively calculating it if it is not set.

The problem is that the user-specified null count is never validated against the actual count of the buffer.

I suggest removing the ability to specify a null-count, and instead always calculating it.
