Struct TransferSubscriptions 

pub struct TransferSubscriptions { /* private fields */ }

Transfers Subscriptions and their MonitoredItems from one Session to another. For example, a Client may need to reopen a Session and then transfer its Subscriptions to that Session. It may also be used by one Client to take over a Subscription from another Client by transferring the Subscription to its Session.

Note that if you call this manually, you will need to register the subscriptions in the subscription state (Session::subscription_state) in order to receive notifications.

See OPC UA Part 4 - Services 5.13.7 for complete description of the service and error responses.
