How to put validation on an array member in a Query Parameter?

[stevenj]

I have a query parameter defined like so:

        #[oai(validator(max_items = "10"))]
        Query(fragment_ids): Query<Vec<FragmentId>>,

FragmentId is a NewType, defined as:

#[derive(NewType)]
#[oai(example = true)]
/// Unique ID of a fragment.
pub(crate) struct FragmentId(String);

impl Example for FragmentId {
    fn example() -> Self {
        Self("0x7db6f91f3c92c0aef7b3dd497e9ea275229d2ab4dba6a1b30ce6b32db9c9c3b2".into())
    }
}

How do I set the maxLength and pattern properties on this string type that's inside the array?

I want pattern to enforce the hex string, and length to enforce the maximum size of this id.
