public static async Client? connect (Source source, ClientSourceType source_type, uint32 wait_for_connected_seconds, Cancellable? cancellable) throws Error
Asynchronously creates a new Client for source and source_type.
The wait_for_connected_seconds argument had been added since 3.16, to let the caller decide how long to wait for the backend
to fully connect to its (possibly remote) data store. This is required due to a change in the authentication process, which is fully
asynchronous and done on the client side, while not every client is supposed to response to authentication requests. In case the backend
will not connect within the set interval, then it is opened in an offline mode. A special value -1 can be used to not wait for the
connected state at all.
Unlike with Client, there is no need to call open after obtaining the Client.
When the operation is finished, callback will be called. You can then call connect.end to
get the result of the operation.
