Struct TransactionSignedNoHash

pub struct TransactionSignedNoHash {
    pub signature: PrimitiveSignature,
    pub transaction: Transaction,
}

Signed transaction without its Hash. Used type for inserting into the DB.

This can by converted to TransactionSigned by calling TransactionSignedNoHash::hash.

Fields

signature: PrimitiveSignature

The transaction signature values

transaction: Transaction

Raw transaction info

Implementations

impl TransactionSignedNoHash

pub fn hash(&self) -> B256

Calculates the transaction hash. If used more than once, it’s better to convert it to TransactionSigned first.

pub fn recover_signer(&self) -> Option<Address>

Recover signer from signature and hash.

Returns None if the transaction’s signature is invalid, see also Self::recover_signer.

pub fn encode_and_recover_unchecked( &self, buffer: &mut Vec<u8>, ) -> Option<Address>

Recover signer from signature and hash without ensuring that the signature has a low s value.

Reuses a given buffer to avoid numerous reallocations when recovering batches. Clears the buffer before use.

Returns None if the transaction’s signature is invalid, see also recover_signer_unchecked.

Optimism

For optimism this will return [Address::ZERO] if the Signature is empty, this is because pre bedrock (on OP mainnet), relay messages to the L2 Cross Domain Messenger were sent as legacy transactions from the zero address with an empty signature, e.g.: https://optimistic.etherscan.io/tx/0x1bb352ff9215efe5a4c102f45d730bae323c3288d2636672eb61543ddd47abad This makes it possible to import pre bedrock transactions via the sender recovery stage.

pub fn with_hash(self) -> TransactionSigned

Converts into a transaction type with its hash: TransactionSigned.

Note: This will recalculate the hash of the transaction.

pub fn recover_signers<'a, T>(txes: T, num_txes: usize) -> Option<Vec<Address>>

where T: IntoParallelIterator<Item = &'a Self> + IntoIterator<Item = &'a Self> + Send,

Recovers a list of signers from a transaction list iterator

Returns None, if some transaction’s signature is invalid, see also Self::recover_signer.

Methods from Deref<Target = Transaction>

pub fn signature_hash(&self) -> B256

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

pub fn kind(&self) -> TxKind

Gets the transaction’s [TxKind], which is the address of the recipient or [TxKind::Create] if the transaction is a contract creation.

pub fn to(&self) -> Option<Address>

Get the transaction’s address of the contract that will be called, or the address that will receive the transfer.

Returns None if this is a CREATE transaction.

pub fn tx_type(&self) -> TxType

Get the transaction’s type

pub fn access_list(&self) -> Option<&AccessList>

Returns the [AccessList] of the transaction.

Returns None for legacy transactions.

pub fn authorization_list(&self) -> Option<&[SignedAuthorization]>

Returns the [SignedAuthorization] list of the transaction.

Returns None if this transaction is not EIP-7702.

pub fn is_dynamic_fee(&self) -> bool

Returns true if the tx supports dynamic fees

pub fn blob_versioned_hashes(&self) -> Option<Vec<B256>>

Blob versioned hashes for eip4844 transaction, for legacy, eip1559, eip2930 and eip7702 transactions this is None

This is also commonly referred to as the “blob versioned hashes” (BlobVersionedHashes).

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 input(&self) -> &Bytes

Get the transaction’s input field.

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: &Signature, 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.
