コントラクト

• Calling notify_one multiple times on Tokio Notify when no tasks are waiting stores at most one permit, so only the first subsequent notified future completes immediately while subsequent futures remain pending
• Calling notify_waiters when no tasks are waiting stores zero permits, leaving subsequent notified futures pending
• Calling notify_waiters wakes all currently registered waiting futures simultaneously
• Calling notify_one wakes exactly one registered waiting future while leaving other registered waiters pending
