[jira] [Created] (SPARK-27174) Support casting integer types to BinaryType

Martin Junghanns created SPARK-27174:
----------------------------------------

             Summary: Support casting integer types to BinaryType
                 Key: SPARK-27174
                 URL: https://issues.apache.org/jira/browse/SPARK-27174
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Martin Junghanns


Currently, only {{StringType}} can be cast to {{BinaryType}}.

Integer types also have a well known two's complement binary representation and can therefore be unambiguously cast to {{BinaryType}}.

This PR adds support for casting

* {{ByteType}}
* {{ShortType}}
* {{IntegerType}}
* {{LongType}}

to {{BinaryType}}.
