Tools for wrapping existing synchronous libraries into Python3's asyncio framework.
Assume that you have some existing libraries with blocking methods:
def foo_sync(x, a, b): """Some existing library methods. Sleeps for x seconds and returns a + b.""" time.sleep(x) return a + b
And you are writing a program in Python3’s asyncio framework. To use the blocking library, one way is to use a thread pool. This library provides another option:
# Wraps foo_sync() into foo_async() to use in asyncio framework. time.sleep = aiowrap.wrap_async(asyncio.sleep) foo_async = aiowrap.wrap_sync(foo_sync)
Now you have an asynchronous, non-blocking version of the method, you can call it inside your favourite coroutine:
async def main(): print(await foo_async(1, 2, 3))
The source code of this example can be found at example/sleep.py.
