Implementations

impl TransactionSigned

pub fn recalculate_hash(&self) -> FixedBytes<32>

Calculate transaction hash, eip2728 transaction does not contain rlp header and start with tx type.

pub fn from_transaction_and_signature( transaction: Transaction, signature: PrimitiveSignature, ) -> TransactionSigned

Create a new signed transaction from a transaction and its signature.

This will also calculate the transaction hash using its encoding.

pub fn decode_rlp_legacy_transaction( data: &mut &[u8], ) -> Result<TransactionSigned, Error>

Decodes legacy transaction from the data buffer.

This should be used only be used in general transaction decoding methods, which have already ensured that the input is a legacy transaction with the following format: rlp(legacy_tx)

Legacy transactions are encoded as lists, so the input should start with a RLP list header.

This expects rlp(legacy_tx)

Methods from Deref<Target = Transaction>

pub fn signature_hash(&self) -> FixedBytes<32>

Heavy operation that return signature hash over rlp encoded transaction. It is only for signature signing or signer recovery.

pub fn tx_type(&self) -> TxType

Get the transaction’s type

pub fn blob_gas_used(&self) -> Option<u64>

Returns the blob gas used for all blobs of the EIP-4844 transaction if it is an EIP-4844 transaction.

This is the number of blobs times the DATA_GAS_PER_BLOB a single blob consumes.

pub fn effective_tip_per_gas(&self, base_fee: Option<u64>) -> Option<u128>

Returns the effective miner gas tip cap (gasTipCap) for the given base fee: min(maxFeePerGas - baseFee, maxPriorityFeePerGas)

If the base fee is None, the max_priority_fee_per_gas, or gas price for non-EIP1559 transactions is returned.

Returns None if the basefee is higher than the [Transaction::max_fee_per_gas].

pub fn encode_for_signing(&self, out: &mut dyn BufMut)

This encodes the transaction without the signature, and is only suitable for creating a hash intended for signing.

pub fn eip2718_encode( &self, signature: &PrimitiveSignature, out: &mut dyn BufMut, )

Produces EIP-2718 encoding of the transaction

pub fn is_legacy(&self) -> bool

Returns true if the transaction is a legacy transaction.

pub fn is_eip2930(&self) -> bool

Returns true if the transaction is an EIP-2930 transaction.

pub fn is_eip1559(&self) -> bool

Returns true if the transaction is an EIP-1559 transaction.

pub fn is_eip4844(&self) -> bool

Returns true if the transaction is an EIP-4844 transaction.

pub fn is_eip7702(&self) -> bool

Returns true if the transaction is an EIP-7702 transaction.

pub fn as_legacy(&self) -> Option<&TxLegacy>

Returns the [TxLegacy] variant if the transaction is a legacy transaction.

pub fn as_eip2930(&self) -> Option<&TxEip2930>

Returns the [TxEip2930] variant if the transaction is an EIP-2930 transaction.

pub fn as_eip1559(&self) -> Option<&TxEip1559>

Returns the [TxEip1559] variant if the transaction is an EIP-1559 transaction.

pub fn as_eip4844(&self) -> Option<&TxEip4844>

Returns the [TxEip4844] variant if the transaction is an EIP-4844 transaction.

pub fn as_eip7702(&self) -> Option<&TxEip7702>

Returns the [TxEip7702] variant if the transaction is an EIP-7702 transaction.

Trait Implementations

impl AsRef<Transaction> for TransactionSigned

fn as_ref(&self) -> &Transaction

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<TransactionSigned> for TransactionSigned

fn as_ref(&self) -> &TransactionSigned

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TransactionSigned

fn clone(&self) -> TransactionSigned

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransactionSigned

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decodable for TransactionSigned

fn decode(buf: &mut &[u8]) -> Result<TransactionSigned, Error>

This Decodable implementation only supports decoding rlp encoded transactions as it’s used by p2p.

The p2p encoding format always includes an RLP header, although the type RLP header depends on whether or not the transaction is a legacy transaction.

If the transaction is a legacy transaction, it is just encoded as a RLP list: rlp(tx-data).

If the transaction is a typed transaction, it is encoded as a RLP string: rlp(tx-type || rlp(tx-data))

This can be used for decoding all signed transactions in p2p BlockBodies responses.

This cannot be used for decoding EIP-4844 transactions in p2p PooledTransactions, since the EIP-4844 variant of TransactionSigned does not include the blob sidecar.

For a method suitable for decoding pooled transactions, see [PooledTransaction].

CAUTION: Due to a quirk in [Header::decode], this method will succeed even if a typed transaction is encoded in this format, and does not start with a RLP header: tx-type || rlp(tx-data).

This is because [Header::decode] does not advance the buffer, and returns a length-1 string header if the first byte is less than 0xf7.

impl Decodable2718 for TransactionSigned

fn typed_decode( ty: u8, buf: &mut &[u8], ) -> Result<TransactionSigned, Eip2718Error>

fn extract_type_byte(buf: &mut &[u8]) -> Option<u8>

fn decode_2718(buf: &mut &[u8]) -> Result<Self, Eip2718Error>
