Types ¶

type Errors ¶

type Errors struct {
	Start     error
	Wait      error // WaitForMastership error.
	IsMaster  error
	Resign    error // ResignAndRestart error.
	Close     error
	GetMaster error // GetCurrentMaster error.
}

Errors contains errors to be returned by each of MasterElection methods.

func ErrAll ¶

func ErrAll(err error) *Errors

ErrAll creates Errors containing the same err associated with each method.

type MasterElection ¶

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

MasterElection implements election.MasterElection interface for testing.

func NewMasterElection ¶

func NewMasterElection(isMaster bool, errs *Errors) *MasterElection

NewMasterElection returns a new initialized MasterElection for testing.

func (*MasterElection) Close ¶

func (e *MasterElection) Close(context.Context) error

Close returns the stored error.

func (*MasterElection) GetCurrentMaster ¶

func (e *MasterElection) GetCurrentMaster(context.Context) (string, error)

GetCurrentMaster returns the current master which is *this* instance, or error if not currently the master.

func (*MasterElection) IsMaster ¶

func (e *MasterElection) IsMaster(context.Context) (bool, error)

IsMaster returns the stored mastership status and error.

func (*MasterElection) Resign ¶

func (e *MasterElection) Resign(context.Context) error

Resign returns the stored error and resets mastership status if the error is nil.

func (*MasterElection) Start ¶

func (e *MasterElection) Start(context.Context) error

Start returns the stored error for this call.

func (*MasterElection) Update ¶

func (e *MasterElection) Update(isMaster bool, errs *Errors)

Update changes mastership status and errors returned by interface calls.

func (*MasterElection) WaitForMastership ¶

func (e *MasterElection) WaitForMastership(ctx context.Context) error

WaitForMastership blocks until this instance is master, or an error is supplied, or context is done.
