| error[E0605]: non-primitive cast: `Foo` as `isize` | |
| --> $DIR/nonscalar-cast.rs:15:20 | |
| | | |
| LL | println!("{}", Foo { x: 1 } as isize); | |
| | ^^^^^^^^^^^^^^^^^^^^^ help: consider using the `From` trait instead: `isize::from(Foo { x: 1 })` | |
| | | |
| = note: an `as` expression can only be used to convert between primitive types or to coerce to a specific trait object | |
