View Source

var ErrLeaseManagerRunning = errors.New("lease manager already running")

ErrLeaseManagerRunning is the error returned by NewLeaseManager if there is already one running.

View Source

var ErrNoLeaseManager = errors.New("no active lease manager")

ErrNoLeaseManager is the error returned by singletonLeaseManager methods if no lease manager is running.

Functions ¶

func Manager ¶

func Manager() *singletonLeaseManager

Manager returns a singleton lease manager, which is active so long as there is a running leaseManager worker.

func NewLeaseManager ¶

func NewLeaseManager(leasePersistor leasePersistor) (*leaseManager, error)

NewLeaseManager returns a new leaseManager, a worker that manages leases. Users may interact with the lease manager while it is running, but will receive an error if the manager has stopped.

Starting a lease manager updates a singleton in this package, so an error will result if NewLeaseManager is called while another lease manager is still active.

Types ¶

type Token ¶

type Token struct {
	Namespace, Id string
	Expiration    time.Time
}

Token represents a lease claim.
