type Options struct {
Broker broker.Broker
Client client.Client
Server server.Server
Registry registry.Registry
Transport transport.Transport
// Before and After funcs
BeforeStart []func() error
BeforeStop []func() error
AfterStart []func() error
AfterStop []func() error
// Other options for implementations of the interface
// can be stored in a context
Context context.Context
}
func NewOptions ¶
type Service ¶
type Service interface {
// The service name
Name() string
// Init initialises options
