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 TransactionsOld ¶
type TransactionsOld []*TransactionOld
Transactions is a Transaction slice type for basic sorting.
func (TransactionsOld) GetRlp ¶
func (s TransactionsOld) GetRlp(i int) []byte
GetRlp implements Rlpable and returns the i'th element of s in rlp.
func (TransactionsOld) Swap ¶
func (s TransactionsOld) Swap(i, j int)
Swap swaps the i'th and the j'th element in s.
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.
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.
