Functions

func Dump

func Dump(
	dataDir, testnet string,
	blockHeight uint64,
	blockHash string,
	defrost bool,
) error

Dump dumps the Ethereum database for the given testnet stored in dataDir up to blockHeight with given blockHash into the evm-bully cache directory:

~/.config/evm-bully/tetstnet/dbdump.

func Open

func Open(
	dataDir, testnet, cacheDir string,
	blockHeight uint64,
	blockHash string,
	defrost bool,
) (ethdb.Database, []common.Hash, error)

Open database.

Types

type Block

type Block struct {
	Header       *types.Header
	Coinbase     common.Address
	Time         uint64
	Hash         common.Hash
	Transactions []*Transaction
}

Block defines an Ethereum block.

type Reader

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

Reader implments a DB dump reader.

func NewReader

func NewReader(testnet string) (*Reader, error)

NewReader returns a new DB dump reader for the given testnet.

func (*Reader) Close

func (r *Reader) Close() error

Close closes the reader.

func (*Reader) Next

func (r *Reader) Next() (*Block, error)

Next returns the next Block for the given reader or nil.

type Transaction

type Transaction struct {
	RLP      []byte
	Nonce    uint64
	GasPrice *big.Int
	GasLimit uint64
	To       *common.Address
	Value    *big.Int
	Data     []byte
}

Transaction defines an Ethereum transaction.
