type AtomWithHashOptions

[AjaxSolutions]

I'm learning AtomWithHashOptions. Does this type make sense? If so, please add it at the next opportunity.

export type AtomWithHashOptions<Value> = {
    /**
     * A function to serialize the value before storing it in the URL hash.
     * The serialized string will be decoded by the `deserialize` function.
     * Default: `JSON.stringify`
     */
    serialize?: (val: Value) => string;
    /**
     * A function to deserialize the value retrieved from the URL hash.
     * The deserialized value will be used as the initial value of the atom.
     * If the deserialized value is `NO_STORAGE_VALUE`, the atom will be initialized with the `initialValue`.
     * Default: `(str) => NO_STORAGE_VALUE`
     */
    deserialize?: (str: string | null) => Value | typeof NO_STORAGE_VALUE;
    /**
     * A boolean flag that indicates whether to use `window.history.replaceState` instead of `window.location.hash`.
     * When this flag is set to `true`, the URL hash will be replaced instead of being added to the browser history.
     * Note: This flag is deprecated in favor of using `setHash` with `"replaceState"`.
     * Default: `false`
     * @deprecated Use `setHash` with 'replaceState' instead
     */
    replaceState?: boolean;
    /**
     * A function that will be called when the URL hash changes.
     * The callback should update the atom value with the new hash value.
     * Default: `(callback) => { window.addEventListener("hashchange", callback); return () => window.removeEventListener("hashchange", callback); }`
     * @returns A function that can be called to unsubscribe from the changes.
     */
    subscribe?: (callback: () => void) => () => void;
    /**
     * A function to set the URL hash.
     * By default, it sets the hash using `window.location.hash`.
     * When `replaceState` is set to true, it uses `window.history.replaceState` instead.
     * If a function is provided, it will be used instead.
     * The searchParams argument is the stringified version of the atom value.
     * Default: `"default"`
     * Options:
     * - `"default"`: Sets the hash using `window.location.hash`.
     * - `"replaceState"`: Sets the hash using `window.history.replaceState`.
     * - `(searchParams: string) => void`: A custom function that will be used to set the hash.
     */
    setHash?: "default" | "replaceState" | ((searchParams: string) => void);
};

Do you want the type exported, or is your concern about jsdoc?
