Types

type EthTxSigner

type EthTxSigner struct {
	Nonce    uint64   // nonce of sender account
	GasPrice *big.Int // wei per gas
	Gas      uint64   // gas limit
	To       *[]byte  `rlp:"nil"` // nil means contract creation
	Value    *big.Int // wei amount
	Data     []byte   // contract invocation input data
	V, R, S  *big.Int // signature values
	// contains filtered or unexported fields

func (*EthTxSigner) EncodeRPL

func (tx *EthTxSigner) EncodeRPL() (data []byte, err error)

func (*EthTxSigner) Hash

func (tx *EthTxSigner) Hash() []byte

func (*EthTxSigner) SetChainId

func (tx *EthTxSigner) SetChainId(id *big.Int)

type KeccakState

type KeccakState interface {
	hash.Hash
	Read([]byte) (int, error)
}

KeccakState wraps sha3.state. In addition to the usual hash methods, it also supports Read to get a variable amount of data from the hash state. Read is faster than Sum because it doesn't copy the internal state, but also modifies the internal state. imported from go-ethereum, modified to remove dependency on go-ethereum/common because "A little copying is better than a little dependency." (https://go-proverbs.github.io) ;)

func NewKeccakState

func NewKeccakState() KeccakState
