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
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
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 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 {
Client client.Client
Server server.Server
// 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
Profile profile.Profile
}
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)
// 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 go-micro. 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.
