Supporting sync code in a Quart Extension
-----------------------------------------

Extension authors can support sync functions by utilising the
:meth:`quart.Quart.ensure_async` method. For example, if the extension
provides a view function decorator add ``ensure_async`` before calling
the decorated function,

.. code-block:: python

    def extension(func):
        @wraps(func)
        async def wrapper(*args, **kwargs):
            ...  # Extension logic
            return await current_app.ensure_async(func)(*args, **kwargs)
        return wrapper
