Package goczmq is a golang binding for CZMQ 3. CZMQ is a high level binding for ZeroMQ. Along with ZeroMQ socket support, CZMQ provides "actor" based services for authentication, service discovery, and creating proxies. GoCZMQ provides direct bindings to CZMQ along with higher level go abstractions such as channels and io.ReadWriter interface support.

if err != nil {
panic(err)
}
fmt.Printf("started beacon on: %s", address)
err = beacon.Publish("HI", 100)
if err != nil {

}
NewBeacon creates a new Beacon instance.
Configure accepts a port number and configures the beacon, returning an address
Destroy destroys the beacon.
Publish publishes an announcement string at an interval
PublishBytes publishes an announcement byte slice at an interval
Recv waits for the specific timeout in milliseconds to receive a beacon
Subscribe subscribes to beacons matching the filter
Verbose sets the beacon to log information to stdout.
type Cert struct {
// contains filtered or unexported fields
}Cert wraps the CZMQ zcert class. It provides tools for creating and working with ZMQ CURVE security certs. The certs can be used as a temporary object in memory or persisted to disk. Certs are made up of a public and secret keypair + metadata.

Print prints a list of certificates in the store to stdout

Code:
// create a dealer channeler dealer := NewDealerChanneler("inproc://channelerdealerrouter") defer dealer.Destroy() // create a router channeler router := NewRouterChanneler("inproc://channelerdealerrouter") defer router.Destroy() // send a hello message dealer.SendChan <- [][]byte{[]byte("Hello")} // receive the hello message request := <-router.RecvChan // first frame is identity of client - let's append 'World' // to the message and route it back request = append(request, []byte("World")) // send the reply router.SendChan <- request // receive the reply reply := <-dealer.RecvChan fmt.Printf("%s %s", string(reply[0]), string(reply[1]))

type Poller struct {
// contains filtered or unexported fields
}Poller provides a simple wrapper to ZeroMQ's zmq_poll API, for the common case of reading from a number of sockets. Sockets can be added and removed from the running poller.
Code:
sock1, err := NewRouter("inproc://poller_example_1")
if err != nil {
panic(err)
}
defer sock1.Destroy()
poller, err := NewPoller(sock1)

NewProxy creates a new Proxy instance.
