async_sync¶

privex.helpers.asyncx.async_sync(f)[source]¶

Async Synchronous Decorator, borrowed from https://stackoverflow.com/a/23036785/2648583 - added this PyDoc comment and support for returning data from a synchronous function

Allows a non-async function to run async functions using yield from - and can also return data

Useful for unit testing, since unittest.TestCase functions are synchronous.

Example async function:

>>> async def my_async_func(a, b, x=None, y=None):
...     return a, b, x, y
...

Using the above async function with a non-async function:

>>> @async_sync
... def sync_function():
...     result = yield from my_async_func(1, 2, x=3, y=4)
...     return result
...
>>> r = sync_function()
>>> print(r)
(1, 2, 3, 4,)
>>> print(r[1])
