3/// Represents the schema for elements in arri
4///
5/// This struct defines the structure of elements, including their serializable
6/// representation, optional metadata, and nullability.
7///
8/// # Fields
9///
10/// * `elements` - A boxed trait object implementing the `Serializable` trait,
11///   representing the serializable content of the elements.
12/// * `metadata` - An optional `MetadataSchema` providing additional information
13///   about the elements.
14/// * `is_nullable` - An optional boolean indicating whether the elements can
15///   be null.
