Types ¶

type EventInfo ¶

type EventInfo struct {
	ID        *ffcapi.EventID
	Confirmed func(ctx context.Context, confirmations []apitypes.BlockInfo)
}

type Manager ¶

type Manager interface {
	Notify(n *Notification) error
	Start()
	Stop()
	NewBlockHashes() chan<- *ffcapi.BlockHashEvent
	CheckInFlight(listenerID *fftypes.UUID) bool
}

Manager listens to the blocks on the chain, and attributes confirmations to pending events. Once those events meet a threshold they are considered final and dispatched to the relevant listener.
