Variable AnySetSchema`Const`

AnySetSchema: ZodUnion<
    [
        ZodCustom<Set<unknown>, Set<unknown>>,
        ZodCustom<WeakSet<WeakKey>, WeakSet<WeakKey>>,
    ],

Schema that matches either Set or WeakSet instances.

This unified schema handles both strong and weak Set types, making it useful for assertions that should work with either variant. The distinction between Set and WeakSet is important for garbage collection behavior but often irrelevant for structural assertions.

Key Differences Between Set and WeakSet:

Set: Holds strong references, prevents GC, iterable, any value types
WeakSet: Holds weak references, allows GC, not iterable, object keys only

Usage Scenarios:

Generic containment checks that work with both types
Polymorphic collection handling in assertion libraries
APIs that accept either Set variant for flexibility

WeakSet Limitations:

Only accepts object or symbol values (primitives will cause runtime errors)
Cannot be iterated or have size checked
Some Set-specific assertions may not work with WeakSet

Example

// Accepts both Set and WeakSet
AnySetSchema.parse(new Set([1, 2, 3])); // ✓ passes
AnySetSchema.parse(new WeakSet([obj1, obj2])); // ✓ passes
AnySetSchema.parse(new Map()); // ✗ fails (wrong collection type)

// Usage in assertions
expect(myWeakSet, 'to contain', someObject); // Works with WeakSet
expect(mySet, 'to contain', 'string'); // Works with Set
