Tools for wrapping existing synchronous libraries into Python3's asyncio framework.

Project description

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.
