helgikrs opened a new issue #1193:
URL: https://github.com/apache/arrow-rs/issues/1193
**Describe the bug**
Pretty printing a record batch containing a float16 column produces an error
```console
panicked at 'called `Option::unwrap()` on a `None` value',
arrow/src/util/display.rs:316:30
```
**To Reproduce**
Create a record batch containing a float16 array and call
`pretty_format_batches` on it, like so:
```rust
let values = vec![
Some(f16::from_f32(f32::NAN)),
Some(f16::from_f32(4.0)),
Some(f16::from_f32(f32::NEG_INFINITY)),
];
let array = Arc::new(values.into_iter().collect::<Float16Array>()) as
ArrayRef;
let schema = Arc::new(Schema::new(vec![Field::new(
"f16",
array.data_type().clone(),
true,
)]));
let batch = RecordBatch::try_new(schema, vec![array])?;
let table = pretty_format_batches(&[batch])?.to_string();
```
**Expected behavior**
Should pretty print the record batch.
