class Server

Create a new network with configurable upstream connectivity.

The network itself is always guaranteed to be created, but upstream

connectivity may not be established initially and may be lost at

any time.

+ request `config` network configuration.

+ request `network` provides control over the created network. The

protocol will be terminated after emitting a terminal event if the

network cannot be added.

|bind_handler| returns a handler that binds incoming connections to this

server implementation.

The returned handler borrows the server instance.

The server must outlive the provided |dispatcher|. Only after

the dispatcher is shutdown will it be safe to destroy the servers.

The server should not be moved.
