type BasicHost

type BasicHost struct {
	// contains filtered or unexported fields

BasicHost is the basic implementation of the host.Host interface. This particular host implementation:

  • uses a protocol muxer to mux per-protocol streams
  • uses an identity service to send + receive node information
  • uses a relay service to allow hosts to relay conns for each other
  • uses a nat service to establish NAT port mappings

func New

func New(net inet.Network, opts ...interface{}) *BasicHost

New constructs and sets up a new *BasicHost with given Network

func (*BasicHost) Addrs

func (h *BasicHost) Addrs() []ma.Multiaddr

Addrs returns all the addresses of BasicHost at this moment in time. It's ok to not include addresses if they're not available to be used now.

func (*BasicHost) Close

func (h *BasicHost) Close() error

Close shuts down the Host's services (network, etc).

func (*BasicHost) Connect

func (h *BasicHost) Connect(ctx context.Context, pi peer.PeerInfo) error

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.

func (*BasicHost) GetBandwidthReporter added in v0.3.2

func (h *BasicHost) GetBandwidthReporter() metrics.Reporter

GetBandwidthReporter exposes the Host's bandiwth metrics reporter

func (*BasicHost) ID

func (h *BasicHost) ID() peer.ID

ID returns the (local) peer.ID associated with this Host

func (*BasicHost) IDService

func (h *BasicHost) IDService() *identify.IDService

IDService returns

func (*BasicHost) Mux

func (h *BasicHost) Mux() *protocol.Mux

Mux returns the Mux multiplexing incoming streams to protocol handlers

func (*BasicHost) Network

func (h *BasicHost) Network() inet.Network

Network returns the Network interface of the Host

func (*BasicHost) NewStream

func (h *BasicHost) NewStream(pid protocol.ID, p peer.ID) (inet.Stream, error)

NewStream opens a new stream to given peer p, and writes a p2p/protocol header with given protocol.ID. If there is no connection to p, attempts to create one. If ProtocolID is "", writes no header. (Threadsafe)

func (*BasicHost) Peerstore

func (h *BasicHost) Peerstore() peer.Peerstore

Peerstore returns the Host's repository of Peer Addresses and Keys.

func (*BasicHost) RemoveStreamHandler

func (h *BasicHost) RemoveStreamHandler(pid protocol.ID)

RemoveStreamHandler returns ..

func (*BasicHost) SetStreamHandler

func (h *BasicHost) SetStreamHandler(pid protocol.ID, handler inet.StreamHandler)

SetStreamHandler sets the protocol handler on the Host's Mux. This is equivalent to:

host.Mux().SetHandler(proto, handler)


type Option

type Option int

Option is a type used to pass in options to the host.

const (
	// NATPortMap makes the host attempt to open port-mapping in NAT devices
	// for all its listeners. Pass in this option in the constructor to
	// asynchronously a) find a gateway, b) open port mappings, c) republish
	// port mappings periodically. The NATed addresses are included in the
	// Host's Addrs() list.
	NATPortMap Option = iota
