How to use the ring.dict function in ring

def storage_dict():

    storage.ring = ring.dict
    storage.is_binary = False
    storage.has_has = True
    storage.has_touch = True
    storage.has_expire = True
    return storage

    @ring.dict({}, ignorable_keys=['ignorable'])

    @ring.dict({})
    async def g(a: int, b: str) -> float:
        pass

    @ring.dict({})
    def f():
        pass

    assert repr(ring.dict)
    assert repr(ring.dict({}))
    assert repr(f)

    @ring.dict(cache, ignorable_keys=['use_cache'])
    def fibonacci(n, use_cache):
        if use_cache:
            raise RuntimeError('it is not cached!')
        if n <= 1:
            return n
        return fibonacci(n - 2, use_cache) + fibonacci(n - 1, use_cache)

    @ring.dict({}, ignorable_keys=['ignorable'])
    def f(n, ignorable):
        return n + ignorable

    @ring.dict({})
    def f():
        pass

    @ring.dict(cache, expire=1)
    def f(a, b):
        return a * 100 + b

        @ring.dict(storage)
        @classmethod
