Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client implements a signaling service client. Tracks a set of ongoing Session RPCs. Manages backpressure on senders across the signaling channel. Manages validating and signing messages with the peer private key.

func NewClient 

func NewClient(
	le *logrus.Entry,
	c signaling_rpc.SRPCSignalingClient,
	privKey crypto.PrivKey,
	backoffConf *backoff.Backoff,
) (*Client, error)

NewClient constructs a new client.

func NewClientWithBus 

func NewClientWithBus(
	le *logrus.Entry,
	b bus.Bus,
	privKey crypto.PrivKey,
	clientConf *stream_srpc_client.Config,
	protocolID protocol.ID,
	serviceID string,
) (*Client, error)

NewClientWithBus constructs a new client that contacts the server via a Bifrost stream.

If protocolID is empty, uses the default signaling protocol id. If serviceID is empty, uses the default signaling service id.

func (*Client) AddPeerRef 

func (c *Client) AddPeerRef(remotePeerID string) *ClientPeerRef

AddPeerRef adds a reference to a remote peer. Initiates a session with the remote peer that can send/recv messages. Be sure to release the ref when done with it.

func (*Client) ClearContext 

func (c *Client) ClearContext()

ClearContext clears the context for the client.

func (*Client) SetContext 

func (c *Client) SetContext(ctx context.Context)

SetContext sets the context for the client. Until this is called, the client will do nothing.

func (*Client) SetListenHandler 

func (c *Client) SetListenHandler(listenHandler ClientListenHandler)

SetListenHandler sets the handler to call when the Listen RPC returns a peer to contact. If nil, disables the Listen RPC.

listenHandler: if set, calls Listen and updates the handler when the list of remote peers that want a session with the local peer changes.

listenHandler is called with reset=true when the list is cleared.

SetContext must also be called to start the Listen RPC routine.

type ClientListenHandler 

type ClientListenHandler func(ctx context.Context, reset, added bool, pid string)

ClientListenHandler is a function to handle when the incoming sessions list changes.

pid is the peer id in string format.

type ClientPeerRef 

type ClientPeerRef struct {
	// contains filtered or unexported fields
}

ClientPeerRef is a reference to a client peer.

func (*ClientPeerRef) GetLocalPeerID 

func (r *ClientPeerRef) GetLocalPeerID() peer.ID

GetLocalPeerID returns the local peer ID.

func (*ClientPeerRef) GetRemotePeerID 

func (r *ClientPeerRef) GetRemotePeerID() peer.ID

GetRemotePeerID returns the remote peer ID.

func (*ClientPeerRef) Recv 

func (r *ClientPeerRef) Recv(ctx context.Context) (*peer.SignedMsg, error)

Recv waits for and acks an incoming message from a remote peer.

func (*ClientPeerRef) Release 

func (r *ClientPeerRef) Release()

Release releases the peer reference.

func (*ClientPeerRef) Send 

func (r *ClientPeerRef) Send(ctx context.Context, msg []byte) (_ *peer.SignedMsg, outErr error)

Send attempts to sign and send a message to the remote peer.

Encodes & signs the data with the peer private key Waits for the remote buffer to be empty Sends the message Waits for the message to be acked

If context is canceled the message will also be canceled.

	ServiceId string `protobuf:"bytes,5,opt,name=service_id,json=serviceId,proto3" json:"service_id,omitempty"`
	// Backoff is the backoff config for connecting to the service.
	// If unset, defaults to reasonable defaults.
	Backoff *backoff.Backoff `protobuf:"bytes,6,opt,name=backoff,proto3" json:"backoff,omitempty"`
	// DisableListen disables listening for incoming sessions.
	// If set, we will only call out, not accept incoming sessions.
	// If false, client will emit HandleSignalPeer directives for incoming sessions.
	DisableListen bool `protobuf:"varint,7,opt,name=disable_listen,json=disableListen,proto3" json:"disable_listen,omitempty"`
	// contains filtered or unexported fields
}
