Version of the service

func WrapCall 

func WrapCall(w ...client.CallWrapper) Option

WrapCall is a convenience method for wrapping a Client CallFunc

func WrapClient 

func WrapClient(w ...client.Wrapper) Option

WrapClient is a convenience method for wrapping a Client with some middleware component. A list of wrappers can be provided. Wrappers are applied in reverse order so the last is executed first.

func WrapHandler 

func WrapHandler(w ...server.HandlerWrapper) Option

WrapHandler adds a handler Wrapper to a list of options passed into the server

type Options 

type Options struct {
	Broker   broker.Broker
	Client   client.Client
	Server   server.Server
	Registry registry.Registry
	Selector selector.Selector

	// 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
}

type Service 

type Service interface {
	Init(...Option)
	Options() Options
	Client() client.Client
	Server() server.Server
	Run() error
	String() string
}

Service is an interface that wraps the lower level libraries within go-micro. Its a convenience method for building and initialising services.

func FromContext
