error[E0277]: the size for values of type `[u8]` cannot be known at compilation time
--> $DIR/suggest-borrow-to-dyn-object.rs:12:11

LL | check(s);
| ^ doesn't have a size known at compile-time

= help: within `OsStr`, the trait `Sized` is not implemented for `[u8]`
= note: required because it appears within the type `OsStr`
= note: required for the cast from `OsStr` to the object type `dyn AsRef<Path>`
help: consider borrowing the value, since `&OsStr` can be coerced into `dyn AsRef<Path>`
