Types

type Handler

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

Handler handles PoW requests of the node and uses local PoW. It refreshes the tips of messages during PoW.

func New

func New(targetScore float64, refreshTipsInterval time.Duration) *Handler

New creates a new PoW handler instance.

func (*Handler) DoPoW

func (h *Handler) DoPoW(ctx context.Context, msg *iotago.Message, parallelism int, refreshTipsFunc ...RefreshTipsFunc) (messageSize int, err error)

DoPoW does the proof-of-work required to hit the target score configured on this Handler. The given iota.Message's nonce is automatically updated.

func (*Handler) PoWType

func (h *Handler) PoWType() string

PoWType returns the fastest available PoW type which gets used for PoW requests

type RefreshTipsFunc

type RefreshTipsFunc = func() (tips hornet.MessageIDs, err error)

RefreshTipsFunc refreshes tips of the message if PoW takes longer than a configured duration.
