---------------------------------

             Summary: [Rus5t] [DataFusion] Add support for explicit casts between signed and unsigned ints
                 Key: ARROW-8910
                 URL: https://issues.apache.org/jira/browse/ARROW-8910
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
            Reporter: Andy Grove
             Fix For: 1.0.0


Add support for explicit casts between signed and unsigned ints.

Note that the type coercion optimizer rule shoud never implicity perform casts between types when data would be lost e.g. from negative value to unsigned type.
