}

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

Required Methods

fn l1_tx_data_fee( &mut self, chain_spec: impl OpHardforks, timestamp: u64, input: &[u8], is_deposit: bool, ) -> Result<U256, BlockExecutionError>

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

Takes

• chain_spec: The chain spec 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: impl OpHardforks, timestamp: u64, input: &[u8], ) -> Result<U256, BlockExecutionError>

Computes the data gas cost for an L2 transaction.

Takes

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

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
