Example for Client Support not working

[code-cro]

In the example for client from where do you pull gen_client::Client?

let (client, server) = local::connect::<gen_client::Client, _, _>(io);

It's generated by #[rpc]

@Aloxaf and i have problem
in the example use extend to get delegate function in rpc implement.
but if i just just need rpc client, why not get function delegate from rpc trait directly?
