    Functions ¶
func NewContext ¶
NewContext returns a new Context with the Service embedded within it.
func RegisterHandler ¶
func RegisterHandler(s server.Server, h interface{}, opts ...server.HandlerOption) error
RegisterHandler is syntactic sugar for registering a handler
func RegisterSubscriber ¶
func RegisterSubscriber(topic string, s server.Server, h interface{}, opts ...server.SubscriberOption) error
RegisterSubscriber is syntactic sugar for registering a subscriber
Types ¶
type Event ¶
type Event interface {
	// Publish publishes a message to the event topic
	Publish(ctx context.Context, msg interface{}, opts ...client.PublishOption) error
}
    Event is used to publish messages to topic
type Function ¶
type Function interface {
	// Inherits Service interface
	Service
	// Done signals to complete execution
	Done() error
	// Handle registers an RPC handler
	Handle(v interface{}) error
	// Subscribe registers a subscriber
	Subscribe(topic string, v interface{}) error
}
    Function is a one time executing Service
func NewFunction ¶
NewFunction returns a new Function for a one time executing Service
type Option ¶
type Option func(*Options)
func BeforeStart ¶
BeforeStart run functions before service starts
func Context ¶
Context specifies a context for the service. Can be used to signal shutdown of the service and for extra option values.
func HandleSignal ¶
HandleSignal toggle automatic installation of the signal handler that traps TERM, INT, and QUIT. Users of this future to disable the signal handler, should control liveness of the service through the context
func RegisterInterval ¶
RegisterInterval specifies the interval on which to re-register
func RegisterTTL ¶
RegisterTTL specifies the TTL to use when registering the service
func WrapCall ¶
func WrapCall(w ...client.CallWrapper) Option
WrapCall is a convenience method for wrapping a Client CallFunc
func WrapClient ¶
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
func WrapSubscriber ¶
func WrapSubscriber(w ...server.SubscriberWrapper) Option
WrapSubscriber adds subscriber Wrapper to a list of options passed into the server
type Options ¶
type Options struct {
	Auth      auth.Auth
	Broker    broker.Broker
	Cmd       cmd.Cmd
	Client    client.Client
	Config    config.Config
	Server    server.Server
	Store     store.Store
	Registry  registry.Registry
	Runtime   runtime.Runtime
	Transport transport.Transport
	Profile   profile.Profile
	// 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
	Signal bool
}
    Options for vine service
type Service ¶
type Service interface {
	// The service name
	Name() string
	// Init initialises options
	Init(...Option)
	// Options returns the current options
	Options() Options
	// Client is used to call services
	Client() client.Client
	// Server is for handling requests and events
	Server() server.Server
	// Run the service
	Run() error
	// The service implementation
	String() string
}
    Service is an interface that wraps the lower level libraries within vine. Its a convenience method for building and initialising services.
func FromContext ¶
FromContext retrieves a Service from the Context.
func NewService ¶
NewService creates and returns a new Service based on the packages within.
