Using rust-libp2p is it possible to send direct message (without awaiting a reply) or a request (with reply) to a peer by its ID using gossip?
Or it’s only viable via streams? In that case what if peer is unreachable by the node? Will other peers propagate it somehow to destination peer?
In my pet project I have a stable leader which broadcasts to peers and awaiting responses from them, other peers do not have to see their peers responses, what is the proper way to implement such behaviour?
