export declare type Listener<T> = (value: T) => void;
export default class Notifier<T> {
    private alive;
    private ref?;
    initialized: boolean;
    private listeners;
    subscribe(callback: Listener<T>): () => void;
    consume(value: T): void;
    hydrate(value: T): void;
    hasValue(): boolean;
    get value(): T;
    destroy(): void;
