> Attempting to print `Date32Array`s (and probably all Date/Time/Timestamp
> array types) using Rust's debug print format macro (`println!("\{:?}",
> date_32_array")`) causes a panic, as shown in the minimum reproducible
> example below:
>
> *Invocation:*
>
> {code:java}
> fn date32_print_panic() {
> let mut date_32_builder = Date32Builder::new(1);
> date_32_builder.append_value(-50).unwrap();
> let date_32_array = date_32_builder.finish();
> println!("{:?}", date_32_array);
> }
> {code}
>
> *Result:*
> {noformat}
> PrimitiveArray<Date32>
> [
> thread 'demo::tests::date32_print_panic' panicked at 'called
> `Option::unwrap()` on a `None` value',
> /home/.../rust/arrow/src/array/array_primitive.rs:226:54
> note: run with `RUST_BACKTRACE=1` environment variable to display a
> backtrace{noformat}
