+// SAFETY: The `__enqueue` implementation in RawWorkItem uses a `work_struct` initialized with the
+// `run` method of this trait as the function pointer because:
+//   - `__enqueue` gets the `work_struct` from the `Work` field, using `T::raw_get_work`.
+//   - The only safe way to create a `Work` object is through `Work::new`.
+//   - `Work::new` makes sure that `T::Pointer::run` is passed to `init_work_with_key`.
+//   - Finally `Work` and `RawWorkItem` guarantee that the correct `Work` field
+//     will be used because of the ID const generic bound. This makes sure that `T::raw_get_work`
+//     uses the correct offset for the `Work` field, and `Work::new` picks the correct
+//     implementation of `WorkItemPointer` for `Arc<T>`.
