type Client

type Client interface {
	// RequestAny synchronously sends request to the first connected peer that matches the specified minVersion in
	// random order.
	// A peer is considered a match if its version is greater than or equal to the specified minVersion
	// Returns errNoPeersMatchingVersion if no peer could be found matching specified version
	RequestAny(minVersion version.Application, request []byte) ([]byte, bool, error)

	// Gossip sends given gossip message to peers
	Gossip(gossip []byte) error
}

Client defines ability to send request / response through the Network
