func (*Transaction) Hash ¶
func (tx *Transaction) Hash() common.Hash
Hash returns the transaction hash.
func (*Transaction) MarshalBinary ¶
func (tx *Transaction) MarshalBinary() ([]byte, error)
MarshalBinary returns the canonical encoding of the transaction. For legacy transactions, it returns the RLP encoding. For EIP-2718 typed transactions, it returns the type and payload.
func (*Transaction) MarshalJSON ¶
func (t *Transaction) MarshalJSON() ([]byte, error)
MarshalJSON marshals as JSON with a hash.
func (*Transaction) Nonce ¶
func (tx *Transaction) Nonce() uint64
Nonce returns the sender account nonce of the transaction.
func (*Transaction) Protected ¶
func (tx *Transaction) Protected() bool
Protected says whether the transaction is replay-protected.
func (*Transaction) RawSignatureValues ¶
func (tx *Transaction) RawSignatureValues() (v, r, s *big.Int)
RawSignatureValues returns the V, R, S signature values of the transaction. The return values should not be modified by the caller.
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 previously cached value.
func (*Transaction) To ¶
func (tx *Transaction) To() *common.Address
To returns the recipient address of the transaction. For contract-creation transactions, To returns nil.
func (*Transaction) UnmarshalBinary ¶
func (tx *Transaction) UnmarshalBinary(b []byte) error
UnmarshalBinary decodes the canonical encoding of transactions. It supports legacy RLP transactions and EIP2718 typed transactions.
func (*Transaction) UnmarshalJSON ¶
func (t *Transaction) UnmarshalJSON(input []byte) error
UnmarshalJSON unmarshals from JSON.
func (*Transaction) Value ¶
func (tx *Transaction) Value() *big.Int
Value returns the ely amount of the transaction.
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 in the [R || S || V] format where V is 0 or 1.
type Transactions ¶
type Transactions []*Transaction
Transactions implements DerivableList for transactions.
func TxDifference ¶
func TxDifference(a, b Transactions) Transactions
TxDifference returns a new set which is the difference between a and b.
func (Transactions) EncodeIndex ¶
func (s Transactions) EncodeIndex(i int, w *bytes.Buffer)
EncodeIndex encodes the i'th transaction to w. Note that this does not check for errors because we assume that *Transaction will only ever contain valid txs that were either constructed by decoding or via public API in this package.
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, baseFee *big.Int) *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 TrieHasher ¶
TrieHasher is the tool used to calculate the hash of derivable list. This is internal, do not use.
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 TxByPriceAndTime ¶
type TxByPriceAndTime []*TxWithMinerFee
TxByPriceAndTime 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 (TxByPriceAndTime) Len ¶
func (s TxByPriceAndTime) Len() int
func (TxByPriceAndTime) Less ¶
func (s TxByPriceAndTime) Less(i, j int) bool
func (*TxByPriceAndTime) Pop ¶
func (s *TxByPriceAndTime) Pop() interface{}
func (*TxByPriceAndTime) Push ¶
func (s *TxByPriceAndTime) Push(x interface{})
func (TxByPriceAndTime) Swap ¶
func (s TxByPriceAndTime) Swap(i, j int)
type TxData ¶
type TxData interface {
// contains filtered or unexported methods
}
TxData is the underlying data of a transaction.
This is implemented by DynamicFeeTx, LegacyTx and AccessListTx.
type TxWithMinerFee ¶
type TxWithMinerFee struct {
// contains filtered or unexported fields
}
TxWithMinerFee wraps a transaction with its gas price or effective miner gasTipCap
func NewTxWithMinerFee ¶
func NewTxWithMinerFee(tx *Transaction, baseFee *big.Int) (*TxWithMinerFee, error)
NewTxWithMinerFee creates a wrapped transaction, calculating the effective miner gasTipCap if a base fee is provided. Returns error in case of a negative effective miner gasTipCap.
