| error[E0200]: the trait `Bar` requires an `unsafe impl` declaration |
| --> $DIR/E0200.rs:5:1 |
| | |
| LL | impl Bar for Foo { } |
| | ^^^^^^^^^^^^^^^^ |
| | |
| = note: the trait `Bar` enforces invariants that the compiler can't check. Review the trait documentation and make sure this implementation upholds those invariants before adding the `unsafe` keyword |
| help: add `unsafe` to this trait implementation |
| | |
| LL | unsafe impl Bar for Foo { } |
