Available on crate feature optimism only.

An extension trait for [L1BlockInfo] that allows us to calculate the L1 cost of a transaction based off of the ChainSpec’s activated hardfork.

Required Methods

fn l1_tx_data_fee( &self, chain_spec: &ChainSpec, timestamp: u64, input: &[u8], is_deposit: bool, ) -> Result<Uint<256, 4>, BlockExecutionError>

Forwards an L1 transaction calculation to revm and returns the gas cost.

Takes

• chain_spec: The ChainSpec for the node.
• timestamp: The timestamp of the current block.
• input: The calldata of the transaction.
• is_deposit: Whether or not the transaction is a deposit.

fn l1_data_gas( &self, chain_spec: &ChainSpec, timestamp: u64, input: &[u8], ) -> Result<Uint<256, 4>, BlockExecutionError>

Computes the data gas cost for an L2 transaction.

Takes

• chain_spec: The ChainSpec for the node.
• timestamp: The timestamp of the current block.
• input: The calldata of the transaction.
