Struct CallFrameBackup 

pub struct CallFrameBackup {
    pub original_accounts_info: FxHashMap<Address, LevmAccount>,
    pub original_account_storage_slots: FxHashMap<Address, FxHashMap<H256, U256>>,
    pub bal_checkpoint: Option<BlockAccessListCheckpoint>,
    pub inserted_code_hashes: Vec<H256>,
}

Fields

original_accounts_info: FxHashMap<Address, LevmAccount>

original_account_storage_slots: FxHashMap<Address, FxHashMap<H256, U256>>

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

impl CallFrameBackup

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

pub fn clear(&mut self)

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).

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

Absorb another backup, keeping the EARLIEST original value for each account/slot (first-seen-wins). Mirrors merge_call_frame_backup_with_parent. Does NOT touch bal_checkpoint (set once at the tx level).

Unlike extend (last-wins HashMap::extend), this preserves the value that was already recorded, which is required when accumulating per-frame backups into a tx-level rollback: the original to restore is the value from before the FIRST frame that modified it.
