Since returns duration since started time

Types

type BaseService

type BaseService struct {
	// contains filtered or unexported fields
}

BaseService implements Service

func NewBaseService

func NewBaseService(self Service, cfg config.Configurator) *BaseService

NewBaseService creates a BaseService

func (*BaseService) AddModule

func (app *BaseService) AddModule(mod module.Module) module.Module

AddModule adds a module to service

func (*BaseService) Busy

func (app *BaseService) Busy() bool

Busy implements Service Busy method

func (*BaseService) Discovery

func (app *BaseService) Discovery() discovery.Discovery

Discovery returns the discovery engine

func (*BaseService) ID

func (app *BaseService) ID() int64

ID implements Service ID method

func (*BaseService) Init

State returns state of service

func (*BaseService) UUID

func (app *BaseService) UUID() string

UUID implements service UUID method

func (*BaseService) Update

func (app *BaseService) Update(now time.Time, dt time.Duration)

Update updates per frame

type ConfigRewriter

type ConfigRewriter interface {
	RewriteConfig(unsafe.Pointer)
}

ConfigRewriter rewrites Config

type DiscoveryContent

type DiscoveryContent struct {
	Config interface{} `json:"config"` // config of service
	State  struct {
		Updated int64  `json:"updated"`
		PID     int    `json:"pid"`   // process id
		State   State  `json:"state"` // run state
		UUID    string `json:"uuid"`  // instance uuid
	} `json:"state"` // runtime state of service
}

DiscoveryContent is the content for registering

type Meta

type Meta interface {
	// ID returns id of service
	ID() int64
	// Name of service
	Name() string
	// Global unique instance id of service
	UUID() string
	// Busy reports whether the service is busy
	Busy() bool
	// State returns state of service
	State() State
}

Meta represents metadata of service

type Service

type Service interface {
	Meta

	// SetState sets state of service
	SetState(state State) error
	// Init initializes the service
	Init() error
	// Start starts the service
	Start() error
	// Shutdown shutdowns the service
	Shutdown() error
}

Service represents a process

type State

type State int

State represents service state

const (
	Closed   State = iota // Closed service
	Running               // Running service
	Stopping              // Stopping service
)

func (State) String
