Method new_unchecked

Create a new [`StructArray`] from the provided parts without validation The length will be inferred from the length of the child arrays. Panics if there are no child arrays. Consider using [`Self::new_unchecked_with_length`] if the length is known to avoid this. # Safety Safe if [`Self::new`] would not panic with the given arguments
