Functions

func GetCommand

func GetCommand() *cobra.Command

func LoadConfigFromFile

func LoadConfigFromFile() (*config.Config, error)

LoadConfigFromFile tries to load configuration file if the config parameter was specified.

Types

type App

type App struct {
	*cobra.Command

	Config *config.Config
	// contains filtered or unexported fields
}

App is the cli app singleton.

func New

func New(opts ...Option) *App

New creates an instance of the spacemesh app.

func (*App) Cleanup

func (app *App) Cleanup(ctx context.Context)

Cleanup stops all app services.

func (*App) Initialize

func (app *App) Initialize() (err error)

Initialize sets up an exit signal, logging and checks the clock, returns error if clock is not in sync.

func (*App) LoadOrCreateEdSigner

func (app *App) LoadOrCreateEdSigner() (*signing.EdSigner, error)

LoadOrCreateEdSigner either loads a previously created ed identity for the node or creates a new one if not exists.

func (*App) SetLogLevel

func (app *App) SetLogLevel(name, loglevel string) error

SetLogLevel updates the log level of an existing logger.

func (*App) Start

func (app *App) Start(ctx context.Context) error

Start starts the Spacemesh node and initializes all relevant services according to command line arguments provided.

func (*App) Started

func (app *App) Started() chan struct{}

type NodeClock

type NodeClock interface {
	LayerToTime(types.LayerID) time.Time
	TimeToLayer(time.Time) types.LayerID
	GenesisTime() time.Time

	CurrentLayer() types.LayerID
	AwaitLayer(types.LayerID) chan struct{}

	Close()
}

NodeClock is an interface to a global system clock that releases ticks on each layer.

type Option

type Option func(app *App)

Option to modify an App instance.

func WithConfig

func WithConfig(conf *config.Config) Option

WithConfig overwrites default App config.

func WithLog

func WithLog(logger log.Log) Option

WithLog enables logger for an App.

type Service

type Service interface {
	Start(ctx context.Context) error
	Close()
}

Service is a general service interface that specifies the basic start/stop functionality.
