RLoop

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.

Installation

pip install rloop

Usage

import asyncio
import rloop

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

Differences from stdlib

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

`call_later` with negative delays

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.
