           let a = Date32Array::from(vec![10000, 17890]);
           let array = Arc::new(a) as ArrayRef;
           let b = cast(&array, &DataType::Timestamp(TimeUnit::Nanosecond, 
None)).unwrap();
           let c = 
b.as_any().downcast_ref::<TimestampNanosecondArray>().unwrap();
       }
   
   thread 'cast::tests::test_cast_date32_to_timestamp' panicked at 'called 
`Result::unwrap()` on an `Err` value: CastError("Casting from Date32 to
