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 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 AfterStart ¶
func BeforeStart ¶
func BeforeStop ¶
func Context ¶
Context specifies a context for the service. Can be used to signal shutdown of the service. Can be used for extra option values.
func HandleSignal ¶
HandleSignal toggles automatic installation of the signal handler that traps TERM, INT, and QUIT. Users of this feature 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 a subscriber Wrapper to a list of options passed into the server
type Options ¶
type Options struct { Broker broker.Broker Cmd cmd.Cmd Client client.Client Server server.Server Registry registry.Registry Transport transport.Transport Selector selector.Selector Config config.Config Logger logger.Logger // 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 }
type Publisher ¶
type Publisher interface {
Publish(ctx context.Context, msg interface{}, opts ...client.PublishOption) error
}
Publisher is syntactic sugar for publishing
type Service ¶
type Service interface { // The service name Name() string // Init initialises options Init(...Option) error // 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 stack-rpc. 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.
