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 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.
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 // Register loop interval RegisterInterval time.Duration // 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 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 { 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 ¶
FromContext retrieves a Service from the Context.
func NewService ¶
NewService creates an returns a new Service based on the packages within.
