• The updated test only asserts the description field but omits a check for the new title (ArrayVec<…>). Add an assertion for box_meta.title to fully validate both metadata fields.

assert_eq!(box_meta.description, Some(format!("1 to {max} items of type {}", <T as Type>::RawElementValueType::name()).as_str()));

Leaking a new Box on every call can lead to unbounded memory growth; consider caching the leaked &str (e.g., using OnceCell or lazy_static) so the description is allocated only once per schema.

i think poem only calls this once to build the openapi schema ? wouldn't this method already be pretty expensive to call over and over
