Types ¶

type L1SafeEvent ¶ added in v1.8.0

type L1SafeEvent struct {
	L1Safe eth.L1BlockRef
}

func (L1SafeEvent) String ¶ added in v1.8.0

func (ev L1SafeEvent) String() string

type L1Tracker ¶

type L1Tracker struct {
	derive.L1Fetcher
	// contains filtered or unexported fields
}

L1Tracker implements the L1Fetcher interface while proactively maintaining a reorg-aware cache of L1 block references by number. This handles the L1UnsafeEvent in order to populate the cache with the latest L1 block references.

func NewL1Tracker ¶

func NewL1Tracker(inner derive.L1Fetcher) *L1Tracker

func (*L1Tracker) L1BlockRefByNumber ¶

func (l *L1Tracker) L1BlockRefByNumber(ctx context.Context, num uint64) (eth.L1BlockRef, error)

func (*L1Tracker) OnEvent ¶ added in v1.9.0

func (st *L1Tracker) OnEvent(ev event.Event) bool

type L1UnsafeEvent ¶ added in v1.8.0

type L1UnsafeEvent struct {
	L1Unsafe eth.L1BlockRef
}

func (L1UnsafeEvent) String ¶ added in v1.8.0

func (ev L1UnsafeEvent) String() string

type Metrics ¶

type Metrics interface {
	RecordL1ReorgDepth(d uint64)
	RecordL1Ref(name string, ref eth.L1BlockRef)
}

type StatusTracker ¶

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

func NewStatusTracker ¶

func NewStatusTracker(log log.Logger, metrics Metrics) *StatusTracker

func (*StatusTracker) L1Head ¶

func (st *StatusTracker) L1Head() eth.L1BlockRef

L1Head is a helper function; the L1 head is closely monitored for confirmation-distance logic.

func (*StatusTracker) OnEvent ¶

func (st *StatusTracker) OnEvent(ev event.Event) bool

func (*StatusTracker) SyncStatus ¶

func (st *StatusTracker) SyncStatus() *eth.SyncStatus

SyncStatus is thread safe, and reads the latest view of L1 and L2 block labels
