-It's because of Rust's move semantics again: We try to move out the `ScreenChar` at `row + 1`. If Rust would allow that, the array would become invalid as it would contain some valid and some moved out values. Fortunately, the `ScreenChar` type meets all criteria for the [Copy trait], so we can fix the problem by adding `#derive(Clone, Copy)` to `ScreenChar`.
