[GitHub] [arrow-rs] martin-g opened a new issue, #1902: `dynamic_types` example does not print the projection

[GitBox <gi...@apache.org>]

martin-g opened a new issue, #1902:
URL: https://github.com/apache/arrow-rs/issues/1902

   **Describe the bug**
   
   https://github.com/apache/arrow-rs/blob/master/arrow/examples/dynamic_types.rs shows how to use and project `RecordBatch`es.
   I think it would be a slightly more useful if it actually prints the original and the projection.
   
   **To Reproduce**
   
   ```
   $ cd arrow
   $ cargo run --example dynamic_types
   ```
   
   **Expected behavior**
   
   Print the `RecordBatch`es, e.g.:
   ```
   +----+-----+
   | id | sum |
   +----+-----+
   | 1  | 2.2 |
   | 2  | 3.3 |
   | 3  | 4.4 |
   | 4  | 5.5 |
   | 5  | 6.6 |
   +----+-----+
   ```
   
   **Additional context**
   N/A
