fn bump_bal_index<DB: Database>(state: &mut &mut State<DB>)Expand description
Bumps the BAL index on a &mut State<DB>.
Used as a BalIndexBumper callback so the
generic BbBlockExecutor can advance
bal_index between sub-events of a segment boundary (post-N’s finish()
and pre-N+1’s apply_pre_execution_changes()) without a trait bound on
DB.
