| error[E0277]: `Dummy` doesn't implement `Debug` |
| --> $DIR/issue-107649.rs:105:5 |
| | |
| 105 | dbg!(lib::Dummy); |
| | ^^^^^^^^^^^^^^^^ `Dummy` cannot be formatted using `{:?}` |
| | |
| = help: the trait `Debug` is not implemented for `Dummy`, which is required by `&Dummy: Debug` |
| = note: add `#[derive(Debug)]` to `Dummy` or manually `impl Debug for Dummy` |
| = note: this error originates in the macro `$crate::format_args_nl` which comes from the expansion of the macro `dbg` (in Nightly builds, run with -Z macro-backtrace for more info) |
| help: consider annotating `Dummy` with `#[derive(Debug)]` |
| --> $DIR/auxiliary/dummy_lib.rs:2:1 |
