eventloop.future¶
Module: eventloop.future
¶
New in version 15.0.
As of pyzmq 15, there is a new Socket subclass that returns Futures for recv methods,
which can be found at zmq.eventloop.future.Socket
.
You can create these sockets by instantiating a Context
from the same module.
These sockets let you easily use zmq with tornado’s coroutines.

from tornado import gen
from zmq.eventloop.future import Context
ctx = Context()
@gen.coroutine
def recv_and_process():
sock = ctx.socket(zmq.PULL)
sock.bind(url)
msg = yield sock.recv_multipart() # waits for msg to be ready
reply = yield async_process(msg)
yield sock.send_multipart(reply)
Classes¶
Context
¶
Context class that creates Future-returning sockets. See zmq.Context
for more info.

for use in coroutines and async applications.
See also
zmq.Socket
for the inherited API.
Poller
¶
Poller subclass that returns Future
