RLoop is an AsyncIO selector event loop implemented in Rust on top of the mio crate.

Warning: RLoop is currently a work in progress and definitely not suited for production usage.

Note: RLoop is available on Unix systems only.

pip install rloop

import asyncio
import rloop

asyncio.set_event_loop_policy(rloop.EventLoopPolicy())
loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)

At current time, when compared with the stdlib's event loop, RLoop doesn't support the following features:

• Unix Domain Sockets
• SSL
• debugging

RLoop also doesn't implement the following methods:

• loop.sendfile
• loop.connect_accepted_socket
• loop.sock_recvfrom
• loop.sock_recvfrom_into
• loop.sock_sendto
• loop.sock_sendfile

While the stdlib's event loop will use the actual delay of callbacks when call_later is used with negative numbers, RLoop will treat those as call_soon, and thus the effective order will follow the invocation order, not the delay.
