func (*Transaction) EncodeRLP 

func (tx *Transaction) EncodeRLP(w io.Writer) error

EncodeRLP implements rlp.Encoder

func (*Transaction) GasAssetID 

func (tx *Transaction) GasAssetID() uint64

GasAssetID returns transaction gas asset id.

func (*Transaction) GasPrice 

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

GasPrice returns transaction gas price.

func (*Transaction) GetActions 

func (tx *Transaction) GetActions() []*Action

GetActions return transaction actons.

func (*Transaction) Hash 

func (tx *Transaction) Hash() common.Hash

Hash hashes the RLP encoding of tx.

func (*Transaction) NewRPCTransaction 

func (tx *Transaction) NewRPCTransaction(blockHash common.Hash, blockNumber uint64, index uint64) *RPCTransaction

NewRPCTransaction returns a transaction that will serialize to the RPC.

func (*Transaction) Size 

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

Size returns the true RLP encoded storage size of the transaction,

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(txs map[common.Name][]*Transaction) *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) 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 []*Transaction

TxByNonce sort by transaction first action nonce

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 []*Transaction

TxByPrice implements both the sort and the heap interface,

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{}

Pop implements heap pop.

func (*TxByPrice) Push 

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

Push implements heap push.

func (TxByPrice) Swap 

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