In Drone<Hovering>, shouldn't land be: fn land(self) -> Drone<Idle> { Drone::<Idle>::from(self) } instead of: fn land(self) -> Drone<Idle

In Drone<Hovering>, shouldn't land be: fn land(self) -> Drone<Idle> { Drone::<Idle>::from(self) } instead of: fn land(self) -> Drone<Idle> { Drone::<Idle>::new() } Otherwise the position assertions in drone_flies fail, because it's looking at the position of a brand new Drone<Idle>, rather than one based on the position you just flew to. Edit: Yes it should. [1] [1] https://github.com/rustype/drone/blob/main/src/drone.rs#L53 https://github.com/rustype/drone/blob/main/src/drone.rs#L53
