Celluloid::ZMQ provides Celluloid actors that can interact with 0MQ sockets.
Underneath, it's built on the CZTop library. Celluloid::ZMQ was
primarily created for the purpose of writing DCell, distributed Celluloid
over 0MQ, so before you go building your own distributed Celluloid systems with
Celluloid::ZMQ, be sure to give DCell a look and decide if it fits your purposes.
It provides different Celluloid::ZMQ::Socket classes which can be initialized
then sent bind or connect. Once bound or connected, the socket can
read or send depending on whether it's readable or writable.
You will need the ZeroMQ library and the CZMQ library installed as it's accessed via FFI. See CZTop for installation instructions.
Supported Rubies are MRI >= 2.2, JRuby >= 9.0.4.0, and Rubinius >= 3.7.
The following 0MQ socket types are supported (see types.rb for more info)
- Req / Rep
- Push / Pull
- Pub / Sub
- Dealer / Router
