wjones127 opened a new issue, #4312:
URL: https://github.com/apache/arrow-rs/issues/4312

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   
   Right now, we bubble up an error like
   
   ```
   AttributeError: 'XXX' object has no attribute '_export_to_c'
   ```
   
   When we instead probably want something more like:
   
   ```
   TypeError: expected `pyarrow.Schema` but got object of type 'XXX'
   ```
   
   **Describe the solution you'd like**
   
   Check for the correct Python type and return the TypeError if applicable.
   
   **Describe alternatives you've considered**
   
   We could support duck typing anything that supports `_export_to_c`, but I don't think that's safe right now. In the future, there may be an improved protocol that would allow better handling: https://github.com/apache/arrow/pull/35739
