Unsubscribe message

[ivanovaleksey]

Hello, I would like to have dynamic subscriptions.

On certain action subscription should be created, it is done by MqttClient::subscribe.
And on another action this subscription should be deleted (as I understand MQTT has UNSUBSCRIBE message for that).

And I just realized that I can't see any method for unsubscribing.

Is there any solution for this?

Thanks.

Unsubscribe does have an implementation in the mqtt311 lib and I have been able to get a branch sending and recieving unsubacks. I think I may have to do some more logic to let rumqtt know that i've unsubbed but it looks as if I no longer get the pubs from that channel.

Actually, with mqtt311 0.2 (the last one) it hits unimplemented. It is an mqtt311 issue but at the moment if you call rumqtt::MqttClient::unsubscribe it panics.

At the moment it is not yet implemented, try callng rumqtt::MqttClient::unsubscribe, it will hit unimplemented here:

rumqtt/src/client/mqttstate.rs
