| error[E0277]: `Rectangle` doesn't implement `Debug` |
| 12 | println!("rect1 is {:?}", rect1); |
| | ^^^^^ `Rectangle` cannot be formatted using `{:?}` |
| = help: the trait `Debug` is not implemented for `Rectangle` |
| = note: add `#[derive(Debug)]` to `Rectangle` or manually `impl Debug for Rectangle` |
| = note: this error originates in the macro `$crate::format_args_nl` (in Nightly builds, run with -Z macro-backtrace for more info) |
| help: consider annotating `Rectangle` with `#[derive(Debug)]` |
