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

func NewFunction(opts ...Option) Function

NewFunction returns a new Function for a one time executing Service

type Option

type Option func(*Options)
