Function cardinality

cardinality<
    L extends number
    | undefined,
    U extends number | undefined = undefined,
>(
    lower: L,
    upper?: U,
): SetFactory<L, U>
Creates a SetFactory with custom cardinality constraints.

Returns a SetFactory that wraps a shape into a SetShape with the specified bounds. A Dictionary model is projected per tag within its language map; every other multi-valued model is held as a singleton [element] tuple, the collection form of the Query grammar. A retrieval Selection is supplied per request in the template, never declared on the shape.
Type Parameters
- L extends number | undefined
  The minimum count constraint type
- U extends number | undefined = undefined
  The maximum count constraint type
Parameters
- lower: L
  Minimum number of expected values
- Optionalupper: U
  Maximum number of expected values
Returns SetFactory<L, U>
An immutable SetFactory with the specified cardinality bounds
Throws
TypeError If lower or upper is negative, or if lower exceeds upper
Example
```
const twoToFive = cardinality(2, 5);
const tags = twoToFive(string());
const items = cardinality(0, 100)(resource(ItemShape));
```
