Struct SwarmBuilder 

pub struct SwarmBuilder<Provider, Phase> { /* private fields */ }

Build a Swarm by combining an identity, a set of Transports and a NetworkBehaviour.

 let swarm = SwarmBuilder::with_new_identity()
     .with_tokio()
     .with_tcp(
         Default::default(),
         (libp2p_tls::Config::new, libp2p_noise::Config::new),

     .with_other_transport(|_key| DummyTransport::<(PeerId, StreamMuxerBox)>::new())?
     .with_dns()?
     .with_websocket(

Adds a TCP based transport.

Note that both security_upgrade and multiplexer_upgrade take function pointers, i.e. they take the function themselves (without the invocation via ()), not the result of the function invocation. See example below.
