Source 
fn binary_dict_to_string_view<K: ArrowDictionaryKeyType, O: OffsetSizeTrait>(
    keys: &PrimitiveArray<K>,
    values: &GenericByteArray<GenericBinaryType<O>>,
    cast_options: &CastOptions<'_>,
) -> Result<ArrayRef, ArrowError>
Expand description

Cast Dict<K, Binary> or Dict<K, LargeBinary> to Utf8View, validating UTF-8 for each dictionary value.

Fast path when all values are valid UTF-8: reuses the values buffer without copying. When some values are invalid and cast_options.safe is true, rows pointing to those values become null. When cast_options.safe is false, returns an error immediately.
