Types

type Dispatcher

type Dispatcher interface {
	contracts.DispatcherServer
	Start() (func() error, error)
}

type DispatcherImpl

type DispatcherImpl struct {
	contracts.UnimplementedDispatcherServer
	// contains filtered or unexported fields
}

func New

func New(fs ...DispatcherOpt) (*DispatcherImpl, error)

func (*DispatcherImpl) Heartbeat

func (s *DispatcherImpl) Heartbeat(ctx context.Context, req *contracts.HeartbeatRequest) (*contracts.HeartbeatResponse, error)

Heartbeat is used to update the last heartbeat time for a worker

func (*DispatcherImpl) Listen

func (s *DispatcherImpl) Listen(request *contracts.WorkerListenRequest, stream contracts.Dispatcher_ListenServer) error

Subscribe handles a subscribe request from a client

func (*DispatcherImpl) ListenV2

func (s *DispatcherImpl) ListenV2(request *contracts.WorkerListenRequest, stream contracts.Dispatcher_ListenV2Server) error
