How to use the aioitertools.types.R function in aioitertools

async def map(fn: Callable[[T], R], itr: AnyIterable[T]) -> AsyncIterator[R]:
    """
    Modify item of a mixed iterable using the given function or coroutine.

    Example:

        async for response in map(func, data):
            ...

    """
    # todo: queue items eagerly
    async for item in iter(itr):
        yield await maybe_await(fn(item))

async def starmap(
    fn: AnyFunction[R], iterable: AnyIterableIterable[Any]
) -> AsyncIterator[R]:
    """
    Yield values from a function using an iterable of iterables for arguments.

    Each iterable contained within will be unpacked and consumed before
    executing the function or coroutine.

    Example:

        data = [(1, 1), (1, 1, 1), (2, 2)]

        async for value in starmap(operator.add, data):
            ...  # 2, 3, 4

    """
    async for itr in iter(iterable):
        args = await list(itr)
