Types

type AddrLocker 

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

AddrLocker provides locks for addresses

func (*AddrLocker) LockAddr 

func (l *AddrLocker) LockAddr(address types.Address)

LockAddr locks an account's mutex. This is used to prevent another tx getting the same nonce until the lock is released. The mutex prevents the (an identical nonce) from being read again during the time that the first transaction is being signed.

func (*AddrLocker) UnlockAddr 

func (l *AddrLocker) UnlockAddr(address types.Address)

UnlockAddr unlocks the mutex of the given account.

func (t *Transactor) SendTransactionWithSignature(chainID uint64, args SendTxArgs, sig []byte) (hash types.Hash, err error)

SendTransactionWithSignature receive a transaction and a signature, serialize them together and propage it to the network. It's different from eth_sendRawTransaction because it receives a signature and not a serialized transaction with signature. Since the transactions is already signed, we assume it was validated and used the right nonce.

func (*Transactor) SetNetworkID 

func (t *Transactor) SetNetworkID(networkID uint64)

SetNetworkID selects a correct network.

func (*Transactor) SetRPC 

func (t *Transactor) SetRPC(rpcClient *rpc.Client, timeout time.Duration)

SetRPC sets RPC params, a client and a timeout
