Store Session

[benidi]

First of all thank you very much for working on this library. I was using the opc library from https://github.com/locka99/opcua. Now I want to use this opc client.
Can you give me an idea of how to store the Session so I can use it in the struct:

pub struct OpcConnector {
    pub opc_client: Arc<Mutex<Client>>,
    opc_session: Option<Arc<Mutex<Session>>>,
}

This is my struct to handle opc methods. For example there is a method for subscribe to new opc nodes.

But my problem is, that I get back a Arc ( let (session, event_loop) = client.connect_to_matching_endpoint(....)) . I don't know how to store this to a Arc<Mutex>.
Or is this completely wrong approach?

Thank you,
