Defining an Array Schema with Unique Values

How would you define an Array Schema that ensures all values are unique?

This would be the filter:

const uniqueValues = S.filter((a: Array<unknown>) => a.length === new Set(a).size || "All values must be unique");

const uniqueValues = S.filter((a: Array<unknown>) => a.length === new Set(a).size || "All values must be unique");
