Struct zkevm_circuits::witness::Transaction

pub struct Transaction {
    pub id: u64,
    pub tx: Transaction,
    /* private fields */
}

Result of the parsing of an Ethereum Transaction.

Fields

id: u64

The transaction id

tx: Transaction

The raw transaction fields

Implementations

impl Transaction

pub fn dummy() -> Transaction

Create a dummy Transaction with zero values

pub fn new( id: u64, call_id: usize, sdb: &StateDB, code_db: &mut CodeDB, eth_tx: &Transaction, is_success: bool ) -> Result<Transaction, Error>

Create a new Self.

pub fn steps(&self) -> &[ExecStep]

Return the list of execution steps of this transaction.

pub fn steps_mut(&mut self) -> &mut Vec<ExecStep>

Return a mutable reference to the list of execution steps of this transaction.

pub fn calls(&self) -> &[Call]

Return the list of calls of this transaction.

pub fn calls_mut(&mut self) -> &mut Vec<Call>

Return a mutable reference to the list containing the calls of this transaction.

pub fn last_step(&self) -> &ExecStep

Return last step in this transaction.

pub fn is_steps_empty(&self) -> bool

Return whether the steps in this transaction is empty

pub fn padding_tx(id: usize) -> Transaction

Constructor for padding tx in tx circuit

Methods from Deref<Target = Transaction>

pub fn sign_data(&self, chain_id: u64) -> Result<SignData, Error>

Return the SignData associated with this Transaction.

pub fn call_data_gas_cost(&self) -> u64

Compute call data gas cost from call data

pub fn intrinsic_gas_cost(&self) -> u64

Compute the intrinsic gas cost

pub fn to_or_zero(&self) -> H160

Get the “to” address. If to is None then zero address

pub fn to_or_contract_addr(&self) -> H160

Get the “to” address. If to is None then compute contract address

pub fn is_create(&self) -> bool

Determine if this transaction is a contract create transaction

pub fn to_response( &self, transaction_index: U64, chain_id: U256, block_number: U64 ) -> Transaction

Convert to transaction response

pub fn gas(&self) -> u64

Convenient method for gas limit

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl Default for Transaction

fn default() -> Transaction

Returns the “default value” for a type.

impl Deref for Transaction

type Target = Transaction

The resulting type after dereferencing.

fn deref(&self) -> &<Transaction as Deref>::Target

Dereferences the value.
