Optimism-specific implementation and utilities for the executor

Traits

RethL1BlockInfo

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.

Functions

extract_l1_info

Extracts the [L1BlockInfo] from the L2 block. The L1 info transaction is always the first transaction in the L2 block.

extract_l1_info_from_tx

Extracts the [L1BlockInfo] from the L1 info transaction (first transaction) in the L2 block.

parse_l1_info

Parses the input of the first transaction in the L2 block, into [L1BlockInfo].

parse_l1_info_tx_bedrock

Parses the calldata of the [L1BlockInfo] transaction pre-Ecotone hardfork.

parse_l1_info_tx_ecotone

Updates the L1 block values for an Ecotone upgraded chain. Params are packed and passed in as raw msg.data instead of ABI to reduce calldata size. Params are expected to be in the following order:

parse_l1_info_tx_isthmus

Updates the L1 block values for an Isthmus upgraded chain. Params are packed and passed in as raw msg.data instead of ABI to reduce calldata size. Params are expected to be in the following order:
