Struct CallFrameBackup 

Source 
pub struct CallFrameBackup {
    pub original_accounts_info: HashMap<H160, LevmAccount, FxBuildHasher>,
    pub original_account_storage_slots: HashMap<H160, HashMap<H256, U256, FxBuildHasher>, FxBuildHasher>,
    pub bal_checkpoint: Option<BlockAccessListCheckpoint>,
    pub inserted_code_hashes: Vec<H256>,
}

Fields§

§original_accounts_info: HashMap<H160, LevmAccount, FxBuildHasher>§original_account_storage_slots: HashMap<H160, HashMap<H256, U256, FxBuildHasher>, FxBuildHasher>§bal_checkpoint: Option<BlockAccessListCheckpoint>

BAL checkpoint for EIP-7928 - used to restore state changes on revert while preserving touched_addresses.

§inserted_code_hashes: Vec<H256>

Code hashes this frame inserted into the by-hash code cache (GeneralizedDatabase::codes) for codes it deployed. Removed from the cache on revert: a stale entry would make a later read of the same hash (from a pre-existing account) hit the cache instead of the store, hiding the read from execution-witness recording (EIP-8025).

Implementations§

Source§

impl CallFrameBackup

Source

pub fn backup_account_info( &mut self, address: H160, account: &LevmAccount, ) -> Result<(), InternalError>

Source

pub fn clear(&mut self)

Source

pub fn extend(&mut self, other: CallFrameBackup)

Merges other into self, per-address. For slots present in both, other’s values win. Callers MUST pass the older/more-original backup as other so the truly-original value is preserved (matches the or_insert semantic in backup_storage_slot).
