func (tx *Transaction) IsOutputTx(lampHeight uint64, eBase *common.Address) bool

func (*Transaction) MarshalJSON 

func (tx *Transaction) MarshalJSON() ([]byte, error)

MarshalJSON encodes the web3 RPC transaction format.

func (*Transaction) Nonce 

func (tx *Transaction) Nonce() uint64

func (*Transaction) Protected 

func (tx *Transaction) Protected() bool

Protected returns whether the transaction is protected from replay protection.

func (*Transaction) RawSignatureValues 

func (tx *Transaction) RawSignatureValues() (*big.Int, *big.Int, *big.Int)

func (*Transaction) Size 

func (tx *Transaction) Size() common.StorageSize

Size returns the true RLP encoded storage size of the transaction, either by encoding and returning it, or returning a previsouly cached value.

func (*Transaction) String 

func (tx *Transaction) String() string

func (*Transaction) To 

func (tx *Transaction) To() *common.Address

To returns the recipient address of the transaction. It returns nil if the transaction is a contract creation.

func (*Transaction) UnmarshalJSON 

func (tx *Transaction) UnmarshalJSON(input []byte) error

UnmarshalJSON decodes the web3 RPC transaction format.

func (*Transaction) Value 

func (tx *Transaction) Value() *big.Int

func (*Transaction) WithSignature 

func (tx *Transaction) WithSignature(signer Signer, sig []byte) (*Transaction, error)

WithSignature returns a new transaction with the given signature. This signature needs to be formatted as described in the yellow paper (v+27).

type Transactions 

type Transactions []*Transaction

Transactions is a Transaction slice type for basic sorting.

func TxDifference 

func TxDifference(a, b Transactions) (keep Transactions)

TxDifference returns a new set t which is the difference between a to b.

func (Transactions) GetRlp 

func (s Transactions) GetRlp(i int) []byte

GetRlp implements Rlpable and returns the i'th element of s in rlp.

func (Transactions) Len 

func (s Transactions) Len() int

Len returns the length of s.

func (Transactions) Swap 

func (s Transactions) Swap(i, j int)

Swap swaps the i'th and the j'th element in s.

type TransactionsByPriceAndNonce 

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

TransactionsByPriceAndNonce represents a set of transactions that can return transactions in a profit-maximizing sorted order, while supporting removing entire batches of transactions for non-executable accounts.

func NewTransactionsByPriceAndNonce 

func NewTransactionsByPriceAndNonce(signer Signer, txs map[common.Address]Transactions) *TransactionsByPriceAndNonce

NewTransactionsByPriceAndNonce creates a transaction set that can retrieve price sorted transactions in a nonce-honouring way.

Note, the input map is reowned so the caller should not interact any more with if after providing it to the constructor.

func (*TransactionsByPriceAndNonce) GetTransactions 

func (t *TransactionsByPriceAndNonce) GetTransactions() map[common.Address]Transactions

GetTransactions returns the total transactions

func (*TransactionsByPriceAndNonce) Peek 

func (t *TransactionsByPriceAndNonce) Peek() *Transaction

Peek returns the next transaction by price.

func (*TransactionsByPriceAndNonce) Pop 

func (t *TransactionsByPriceAndNonce) Pop()

Pop removes the best transaction, *not* replacing it with the next one from the same account. This should be used when a transaction cannot be executed and hence all subsequent ones should be discarded from the same account.

func (*TransactionsByPriceAndNonce) Shift 

func (t *TransactionsByPriceAndNonce) Shift()

Shift replaces the current best head with the next one from the same account.

type TxByNonce 

type TxByNonce Transactions

TxByNonce implements the sort interface to allow sorting a list of transactions by their nonces. This is usually only useful for sorting transactions from a single account, otherwise a nonce comparison doesn't make much sense.

func (TxByNonce) Len 

func (s TxByNonce) Len() int

func (TxByNonce) Less 

func (s TxByNonce) Less(i, j int) bool

func (TxByNonce) Swap 

func (s TxByNonce) Swap(i, j int)

type TxByPrice 

type TxByPrice Transactions

TxByPrice implements both the sort and the heap interface, making it useful for all at once sorting as well as individually adding and removing elements.

func (TxByPrice) Len 

func (s TxByPrice) Len() int

func (TxByPrice) Less 

func (s TxByPrice) Less(i, j int) bool

func (*TxByPrice) Pop 

func (s *TxByPrice) Pop() interface{}

func (*TxByPrice) Push 

func (s *TxByPrice) Push(x interface{})

func (TxByPrice) Swap 

func (s TxByPrice) Swap(i, j int)
