Types

type EngineController 

type EngineController interface {
	// SafeBlockAtTimestamp returns the L2 block ref for the block at or before the given timestamp,
	// clamped to the current SAFE head.
	SafeBlockAtTimestamp(ctx context.Context, ts uint64) (eth.L2BlockRef, error)
	// OutputV0AtBlockNumber returns the output preimage for the given L2 block number.
	OutputV0AtBlockNumber(ctx context.Context, num uint64) (*eth.OutputV0, error)
	// Close releases any underlying RPC resources.
	Close() error
}

func NewEngineControllerFromConfig(ctx context.Context, log gethlog.Logger, vncfg *opnodecfg.Config) (EngineController, error)

func NewEngineControllerWithL2(l2 l2Provider) EngineController

NewEngineControllerWithL2 wraps an existing L2 provider.
