| error[E0038]: the trait `Tr` cannot be made into an object |

| LL | trait Tr { |
| | -- this trait cannot be made into an object... |
| LL | fn foo(); |

| ... |
| LL | let _: &dyn Tr = &St; |
| | ^^^ the trait `Tr` cannot be made into an object |
| | |
| = note: required because of the requirements on the impl of `CoerceUnsized<&dyn Tr>` for `&St` |
| = note: required by cast to type `&dyn Tr` |
| help: consider turning `foo` into a method by giving it a `&self` argument or constraining it so it does not apply to trait objects |

| LL | fn foo() where Self: Sized; |
| | ^^^^^^^^^^^^^^^^^ |
