L1MessageQueueMetaData contains all meta data concerning the L1MessageQueue contract.

Types

type BridgeClient 

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

BridgeClient is a wrapper around EthClient that adds methods for conveniently collecting L1 messages.

type EthClient 

type EthClient interface {
	BlockNumber(ctx context.Context) (uint64, error)
	ChainID(ctx context.Context) (*big.Int, error)
	FilterLogs(ctx context.Context, q ethereum.FilterQuery) ([]types.Log, error)
	HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)
	SubscribeFilterLogs(ctx context.Context, query ethereum.FilterQuery, ch chan<- types.Log) (ethereum.Subscription, error)
	TransactionByHash(ctx context.Context, txHash common.Hash) (tx *types.Transaction, isPending bool, err error)
}

We cannot use ethclient.Client directly as that would lead to circular dependency between eth, rollup, and ethclient.

type L1MessageQueueFilterer 

type L1MessageQueueFilterer struct {
	// contains filtered or unexported fields
}

L1MessageQueueFilterer is an auto generated log filtering Go binding around an Ethereum contract events.

func NewL1MessageQueueFilterer 

func NewL1MessageQueueFilterer(address common.Address, filterer bind.ContractFilterer) (*L1MessageQueueFilterer, error)

NewL1MessageQueueFilterer creates a new log filterer instance of L1MessageQueue, bound to a specific deployed contract.

func (*L1MessageQueueFilterer) FilterQueueTransaction 

func (_L1MessageQueue *L1MessageQueueFilterer) FilterQueueTransaction(opts *bind.FilterOpts, sender []common.Address, target []common.Address) (*L1MessageQueueQueueTransactionIterator, error)

FilterQueueTransaction is a free log retrieval operation binding the contract event 0x69cfcb8e6d4192b8aba9902243912587f37e550d75c1fa801491fce26717f37e.

Solidity: event QueueTransaction(address indexed sender, address indexed target, uint256 value, uint64 queueIndex, uint256 gasLimit, bytes data)

type L1MessageQueueQueueTransaction 

type L1MessageQueueQueueTransaction struct {
	Sender     common.Address
	Target     common.Address
	Value      *big.Int
	QueueIndex uint64
	GasLimit   *big.Int
	Data       []byte
	Raw        types.Log // Blockchain specific contextual infos
}

L1MessageQueueQueueTransaction represents a QueueTransaction event raised by the L1MessageQueue contract.

type L1MessageQueueQueueTransactionIterator 

type L1MessageQueueQueueTransactionIterator struct {
	Event *L1MessageQueueQueueTransaction // Event containing the contract specifics and raw log
	// contains filtered or unexported fields
}

L1MessageQueueQueueTransactionIterator is returned from FilterQueueTransaction and is used to iterate over the raw logs and unpacked data for QueueTransaction events raised by the L1MessageQueue contract.

func (*L1MessageQueueQueueTransactionIterator) Close 

func (it *L1MessageQueueQueueTransactionIterator) Close() error

Close terminates the iteration process, releasing any pending underlying resources.

func (*L1MessageQueueQueueTransactionIterator) Error 

func (it *L1MessageQueueQueueTransactionIterator) Error() error

Error returns any retrieval or parsing error occurred during filtering.

func (*L1MessageQueueQueueTransactionIterator) Next 

func (it *L1MessageQueueQueueTransactionIterator) Next() bool

Next advances the iterator to the subsequent event, returning whether there are any more events found. In case of a retrieval or parsing error, false is returned and Error() can be queried for the exact failure.

type SyncService 

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

SyncService collects all L1 messages and stores them in a local database.

func NewSyncService 

func NewSyncService(ctx context.Context, genesisConfig *params.ChainConfig, nodeConfig *node.Config, db ethdb.Database, l1Client EthClient) (*SyncService, error)

func (*SyncService) Start 

func (s *SyncService) Start()

func (*SyncService) Stop 

func (s *SyncService) Stop()

func (*SyncService) SubscribeNewL1MsgsEvent 

func (s *SyncService) SubscribeNewL1MsgsEvent(ch chan<- core.NewL1MsgsEvent) event.Subscription

SubscribeNewL1MsgsEvent registers a subscription of NewL1MsgsEvent and starts sending event to the given channel.
