Requestor

[Wondertan]

Context

As explained in README, the most popular libp2p pattern is request/response and the goal here is to provide utility for it.

Design

type Requestor struct { 
// some private fields 
}
// NewRequestor instantiates new Requestor for a given protocol ID with specified request and response
// message types.
NewRequestor(protocol.Id, serde.Message, serde.Message) *Requestor

// Request sends the request as given message, blocks until a message is written, and returns a       
// channel awaiting for a response. 
// NOTE: This can also be done in fully non-blocking fashion if needed.
func (r *Requestor) Request(peer.ID, serde.Message) <-chan serde.Message, error
