weakref/script/iterable_weak_set.d.ts

IterableWeakSet, IterableWeakMap, and WeakValueMap provide iterable weak collections whose entries disappear automatically when their objects are garbage collected—perfect for caches and registries in any JavaScript runtime.

export declare class IterableWeakSet<T extends object> implements WeakSet<T>, Omit<Set<T>, "add" | "forEach" | "union" | "intersection" | "difference" | "symmetricDifference" | "isSubsetOf" | "isSupersetOf" | "isDisjointFrom"> {
    #private;
    constructor(values?: readonly T[] | null);
    constructor(iterable: Iterable<T>);
    get size(): number;
    add(value: T): this;
    clear(): void;
    delete(value: T): boolean;
    has(value: T): boolean;
    forEach(callbackfn: (value: T, value2: T, set: IterableWeakSet<T>) => void, thisArg?: unknown): void;
    get [Symbol.toStringTag](): string;
    [Symbol.iterator](): SetIterator<T>;
    entries(): SetIterator<[T, T]>;
    keys(): SetIterator<T>;
    values(): SetIterator<T>;
