Struct PrepareRegionBackupMarker 

Source 
pub struct PrepareRegionBackupMarker { /* private fields */ }
Expand description

Snapshot of call_frame_backup’s key-space taken by VM::enter_prepare_region at the start of the atomic prepare region (EIP-8037 auth + prepare-dispatch charges). original_accounts_info / original_account_storage_slots are first-write-wins maps keyed by address, so a plain entry-count marker can’t tell which keys are region-added; recording the pre-region key sets lets VM::fail_prepare_region revert exactly the region’s writes while leaving the earlier sender nonce-bump / fee-deduction backup entries intact. inserted_code_hashes is an append-only Vec, so its pre-region length is enough to identify the region-added tail.
