Functions ¶
func BloomLookup ¶
func CalcUncleHash ¶ added in v0.9.34
func DeriveSha ¶
func DeriveSha(list DerivableList) common.Hash
func SortByPriceAndNonce ¶ added in v1.3.4
func SortByPriceAndNonce(txs []*Transaction)
SortByPriceAndNonce sorts the transactions by price in such a way that the nonce orderings within a single account are maintained.
Note, this is not as trivial as it seems from the first look as there are three different criteria that need to be taken into account (price, nonce, account match), which cannot be done with any plain sorting method, as certain items cannot be compared without context.
This method first sorts the separates the list of transactions into individual sender accounts and sorts them by nonce. After the account nonce ordering is satisfied, the results are merged back together by price, always comparing only the head transaction from each account. This is done via a heap to keep it fast.
Types ¶
type Block ¶
type Block struct { // ReceivedAt is used by package eth to track block propagation time. ReceivedAt time.Time // contains filtered or unexported fields }
func NewBlock ¶ added in v0.8.5
func NewBlock(header *Header, txs []*Transaction, uncles []*Header, receipts []*Receipt) *Block

The values of TxHash, UncleHash, ReceiptHash and Bloom in header are ignored and set to values derived from the given txs, uncles and receipts.
func NewBlockWithHeader ¶ added in v0.8.5
NewBlockWithHeader creates a block with the given header data. The header data is copied, changes to header and to the field values will not affect the block.
func (*Block) DeprecatedTd ¶ added in v1.2.2
DeprecatedTd is an old relic for extracting the TD of a block. It is in the code solely to facilitate upgrading the database from the old format to the new, after which it should be deleted. Do not use!

func (*Header) HashNoNonce ¶ added in v0.8.5

type Receipt struct { // Consensus fields PostState []byte CumulativeGasUsed *big.Int Bloom Bloom Logs vm.Logs // Implementation fields TxHash common.Hash ContractAddress common.Address GasUsed *big.Int }
Receipt represents the results of a transaction.
func NewReceipt ¶
NewReceipt creates a barebone transaction receipt, copying the init fields.
func (*Receipt) DecodeRLP ¶ added in v0.9.26
DecodeRLP implements rlp.Decoder, and loads the consensus fields of a receipt from an RLP stream.
func (*Receipt) EncodeRLP ¶ added in v0.9.17
EncodeRLP implements rlp.Encoder, and flattens the consensus fields of a receipt into an RLP stream.
type ReceiptForStorage ¶ added in v0.9.26
type ReceiptForStorage Receipt
ReceiptForStorage is a wrapper around a Receipt that flattens and parses the entire content of a receipt, as opposed to only the consensus fields originally.
type Receipts ¶
type Receipts []*Receipt
Receipts is a wrapper around a Receipt array to implement types.DerivableList.
type StorageBlock ¶ added in v0.9.17
type StorageBlock Block
[deprecated by eth/63] StorageBlock defines the RLP encoding of a Block stored in the state database. The StorageBlock encoding contains fields that would otherwise need to be recomputed.
type Transaction ¶
type Transaction struct {
// contains filtered or unexported fields
}
func NewContractCreation ¶ added in v0.9.34
func NewContractCreation(nonce uint64, amount, gasLimit, gasPrice *big.Int, data []byte) *Transaction
func NewTransaction ¶ added in v0.9.34

func (tx *Transaction) Cost() *big.Int
Cost returns amount + gasprice * gaslimit.
func (*Transaction) Data ¶
func (tx *Transaction) Data() []byte
func (*Transaction) DecodeRLP ¶ added in v0.9.34
func (tx *Transaction) DecodeRLP(s *rlp.Stream) error
func (*Transaction) EncodeRLP ¶ added in v0.9.34

func (tx *Transaction) From() (common.Address, error)
From returns the address derived from the signature (V, R, S) using secp256k1 eliptic curve and an error if it failed deriving or upon an incorrect signature.
From Uses the homestead consensus rules to determine whether the signature is valid.
From caches the address, allowing it to be used regardless of Frontier / Homestead. however, the first time called it runs signature validations, so we need two versions. This makes it easier to ensure backwards compatibility of things like package rpc where eth_getblockbynumber uses tx.From() and needs to work for both txs before and after the first homestead block. Signatures valid in homestead are a subset of valid ones in Frontier)
func (*Transaction) FromFrontier ¶ added in v1.3.4
func (tx *Transaction) FromFrontier() (common.Address, error)
FromFrontier returns the address derived from the signature (V, R, S) using secp256k1 eliptic curve and an error if it failed deriving or upon an incorrect signature.
FromFrantier uses the frontier consensus rules to determine whether the signature is valid.
FromFrontier caches the address, allowing it to be used regardless of Frontier / Homestead. however, the first time called it runs signature validations, so we need two versions. This makes it easier to ensure backwards compatibility of things like package rpc where eth_getblockbynumber uses tx.From() and needs to work for both txs before and after the first homestead block.

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.
