func (*TransactionsByPriceAndNonce) Pop ¶ added in v1.4.17 

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 ¶ added in v1.4.17 

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 ¶ added in v1.3.4 

func (s TxByNonce) Len() int

func (TxByNonce) Less ¶ 

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

func (TxByNonce) Swap ¶ added in v1.3.4 

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

type TxByPrice ¶ added in v1.0.1 

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 ¶ added in v1.3.4 

func (s TxByPrice) Len() int

func (TxByPrice) Less ¶ added in v1.0.1 

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

func (*TxByPrice) Pop ¶ added in v1.3.4 

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

func (*TxByPrice) Push ¶ added in v1.3.4 

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

func (TxByPrice) Swap ¶ added in v1.3.4 

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