Variables

var DefaultWebRTCConfiguration = webrtc.Configuration{
	ICEServers: []webrtc.ICEServer{
		{
			URLs: []string{"stun:global.stun.twilio.com:3478"},
		},
	},
}

DefaultWebRTCConfiguration is the default configuration to use.

var UnimplementedError = status.Error(codes.Unimplemented, codes.Unimplemented.String())

UnimplementedError is returned any time a gRPC method is unimplemented.

Functions

func Dial

func Dial(ctx context.Context, address string, logger logging.Logger, opts ...rpc.DialOption) (rpc.ClientConn, error)

Dial dials a gRPC server. `ctx` can be used to set a timeout/deadline for Dial. However, the signaling server may have other timeouts which may prevent the full timeout from being respected.

func InferSignalingServerAddress

func InferSignalingServerAddress(address string) (string, bool, bool)

InferSignalingServerAddress returns the appropriate WebRTC signaling server address if it can be detected. Returns the address, if the endpoint is secure, and if found. TODO(RSDK-235): remove hard coding of signaling server address and prefer SRV lookup instead.

Types

type ForeignResource

type ForeignResource struct {
	resource.Named
	resource.TriviallyCloseable
	// contains filtered or unexported fields
}

An ForeignResource is used to dynamically invoke RPC calls to resources that have their RPC information dervied on demand.

func NewForeignResource

func NewForeignResource(name resource.Name, conn rpc.ClientConn) *ForeignResource

NewForeignResource returns an ForeignResource for the given resource name and connection serving it.

func (*ForeignResource) NewStub

func (res *ForeignResource) NewStub() grpcdynamic.Stub

NewStub returns a new gRPC client stub used to communicate with the resource.

func (*ForeignResource) Reconfigure

func (res *ForeignResource) Reconfigure(ctx context.Context, deps resource.Dependencies, conf resource.Config) error

Reconfigure always fails.
