Functions ¶
func InfoFromHost ¶
InfoFromHost returns a peer.AddrInfo struct with the Host's ID and all of its Addrs.
Types ¶
type Host ¶
type Host interface { // ID returns the (local) peer.ID associated with this Host ID() peer.ID // Peerstore returns the Host's repository of Peer Addresses and Keys. Peerstore() peerstore.Peerstore // Returns the listen addresses of the Host Addrs() []ma.Multiaddr // Networks returns the Network interface of the Host Network() network.Network // Mux returns the Mux multiplexing incoming streams to protocol handlers Mux() protocol.Switch // Connect ensures there is a connection between this host and the peer with // given peer.ID. Connect will absorb the addresses in pi into its internal // peerstore. If there is not an active connection, Connect will issue a // h.Network.Dial, and block until a connection is open, or an error is // returned. // TODO: Relay + NAT. Connect(ctx context.Context, pi peer.AddrInfo) error // SetStreamHandler sets the protocol handler on the Host's Mux. // This is equivalent to: // host.Mux().SetHandler(proto, handler) // (Thread-safe) SetStreamHandler(pid protocol.ID, handler network.StreamHandler) // SetStreamHandlerMatch sets the protocol handler on the Host's Mux // using a matching function for protocol selection. SetStreamHandlerMatch(protocol.ID, func(protocol.ID) bool, network.StreamHandler) // RemoveStreamHandler removes a handler on the mux that was set by // SetStreamHandler RemoveStreamHandler(pid protocol.ID) // NewStream opens a new stream to given peer p, and writes a p2p/protocol // header with given ProtocolID. If there is no connection to p, attempts // to create one. If ProtocolID is "", writes no header. // (Thread-safe) NewStream(ctx context.Context, p peer.ID, pids ...protocol.ID) (network.Stream, error) // Close shuts down the host, its Network, and services. Close() error // ConnManager returns this hosts connection manager ConnManager() connmgr.ConnManager // EventBus returns the hosts eventbus EventBus() event.Bus }
Host is an object participating in a p2p network, which implements protocols or provides services. It handles requests like a Server, and issues requests like a Client. It is called Host because it is both Server and Client (and Peer may be confusing).
