```diff

If you are creating entities manually in production, don't do that!
Use `Entities::alloc` instead.
But if you must create one manually, either reuse a `EntityRow` you know to be valid by using `Entity::from_row` and `Entity::row`, or handle the error case of `None` returning from `Entity::from_row_u32(my_index)`.
