Struct RollbackMark 

pub struct RollbackMark(/* private fields */);

An opaque log-length marker (ST-036) — see UndoLog::checkpoint_marker. The wrapped index is absolute over the log’s entire lifetime (it includes entries UndoLog::fossil_collect has already trimmed), never merely an index into the log’s currently retained Vec — see UndoLog::rollback_to’s own doc comment for why that distinction is what makes the fossil-horizon check correct.
