Types

type DoneEvent

type DoneEvent struct {
	Latest *types.Header
}

type FailedEvent

type PublicDownloaderAPI

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

func NewPublicDownloaderAPI

func NewPublicDownloaderAPI(l *snapleecher.Leecher, m *event.TypeMux) *PublicDownloaderAPI

NewPublicDownloaderAPI create a new PublicDownloaderAPI. The API has an internal event loop that listens for events from the downloader through the global event mux. In case it receives one of these events it broadcasts it to all syncing subscriptions that are installed through the installSyncSubscription channel.

func (*PublicDownloaderAPI) SubscribeSyncStatus

func (api *PublicDownloaderAPI) SubscribeSyncStatus(status chan interface{}) *SyncStatusSubscription

SubscribeSyncStatus creates a subscription that will broadcast new synchronisation updates. The given channel must receive interface values, the result can either

func (*PublicDownloaderAPI) Syncing

func (api *PublicDownloaderAPI) Syncing(ctx context.Context) (*rpc.Subscription, error)

Syncing provides information when this nodes starts synchronising with the Ethereum network and when it's finished.

type StartEvent

type StartEvent struct{}

type SyncStatusSubscription

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

type SyncingResult

type SyncingResult struct {
	Syncing bool                  `json:"syncing"`
	Status  ethereum.SyncProgress `json:"status"`
}

SyncingResult provides information about the current synchronisation status for this node.
