Functions

func AttributesMatchBlock

func AttributesMatchBlock(rollupCfg *rollup.Config, attrs *eth.PayloadAttributes, parentHash common.Hash, envelope *eth.ExecutionPayloadEnvelope, l log.Logger) error

AttributesMatchBlock checks if the L2 attributes pre-inputs match the output nil if it is a match. If err is not nil, the error contains the reason for the mismatch

Types

type AttributesHandler

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

func NewAttributesHandler

func NewAttributesHandler(log log.Logger, cfg *rollup.Config, ec Engine, l2 L2) *AttributesHandler

func (*AttributesHandler) HasAttributes

func (eq *AttributesHandler) HasAttributes() bool

func (*AttributesHandler) Proceed

func (eq *AttributesHandler) Proceed(ctx context.Context) error

Proceed processes block attributes, if any. Proceed returns io.EOF if there are no attributes to process. Proceed returns a temporary, reset, or critical error like other derivers. Proceed returns no error if the safe-head may have changed.

func (*AttributesHandler) SetAttributes

func (eq *AttributesHandler) SetAttributes(attributes *derive.AttributesWithParent)

type Engine

type Engine interface {
	derive.EngineControl

	SetUnsafeHead(eth.L2BlockRef)
	SetSafeHead(eth.L2BlockRef)
	SetBackupUnsafeL2Head(block eth.L2BlockRef, triggerReorg bool)
	SetPendingSafeL2Head(eth.L2BlockRef)

	PendingSafeL2Head() eth.L2BlockRef
	BackupUnsafeL2Head() eth.L2BlockRef
}

type L2

type L2 interface {
	PayloadByNumber(context.Context, uint64) (*eth.ExecutionPayloadEnvelope, error)
}
