/// # gneiss::__doctest_slices!();
/// # struct AlarmReason;
/// # impl From<Cookie> for AlarmReason { fn from(_: Cookie) -> Self { AlarmReason } }

/// #[gneiss::service(WakeupService)]
/// fn on_wake(id: WakeupId, cookie: Cookie) {
///     match (id, cookie) {
///         (WakeupId(1), cookie) => handle_alarm_one(AlarmReason::from(cookie)),
