Asyncio event loop based on tokio-rs (WIP) |Build Status| |Join the dev chat at https://gitter.im/PyO3/Lobby|

async-tokio is a drop-in replacement of the built-in asyncio event loop. async-tokio is implemented in rust and uses tokio-rs under the hood and PyO3 python binding <https://github.com/PyO3/pyo3>_.

Using tokio loop

You can create an instance of the loop manually, using:

.. code:: python

import tokio

policy = tokio.EventLoopPolicy()
asyncio.set_event_loop_policy(policy)

Development of tokio loop

To build tokio loop, you'll need rust nightly and Python 3.6. The best way is to create a virtual env, so that you'll have python commands pointing to the correct tools.

1. git clone [email protected]:PyO3/tokio.git

2. cd tokio

3. make build

4. make test

Status

At the moment async-tokio works on unix like systems only. Supported api:

• time api (call_at, call_later)
• sockets api (sock_xxx methods)
• tcp (client/server)
• unix domain socket
• dns
• pipes
• subprocess
• signals
• executors

UDP support is missing.
