Struct reth::core::primitives::transaction::TransactionSignedNoHash

pub struct TransactionSignedNoHash {
    pub signature: Signature,
    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: Signature

The transaction signature values

transaction: Transaction

Raw transaction info

Implementations

impl TransactionSignedNoHash

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

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.

Re-uses 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 Signature::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 TransactionSignedNoHash> + IntoIterator<Item = &'a TransactionSignedNoHash> + 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) -> FixedBytes<32>

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

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

Get chain_id.

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 value(&self) -> Uint<256, 4>

Gets the transaction’s value field.

This is also commonly referred to as the “Gas Fee Cap” (GasFeeCap).

pub fn max_priority_fee_per_gas(&self) -> Option<u128>

Max priority fee per gas for eip1559 transaction, for legacy and eip2930 transactions this is None

This is also commonly referred to as the “Gas Tip Cap” (GasTipCap).

pub fn blob_versioned_hashes(&self) -> Option<Vec<FixedBytes<32>>>

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

pub fn max_fee_per_blob_gas(&self) -> Option<u128>

Max fee per blob gas for eip4844 transaction TxEip4844.

Returns None for non-eip4844 transactions.

This is also commonly referred to as the “Blob Gas Fee Cap” (BlobGasFeeCap).

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 priority_fee_or_price(&self) -> u128

Return the max priority fee per gas if the transaction is an EIP-1559 transaction, and otherwise return the gas price.

Warning

This is different than the max_priority_fee_per_gas method, which returns None for non-EIP-1559 transactions.

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

Returns the effective gas price for the given base fee.

If the transaction is a legacy or EIP2930 transaction, the gas price is returned.

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 source_hash(&self) -> Option<FixedBytes<32>>

Inner encoding function that is used for both rlp [Encodable] trait and for calculating hash that for eip2718 does not require rlp header
