--> $DIR/tag-variant-cast-non-nullary.rs:19:15 | |
| | |
LL | let val = v as isize; | |
| ^^^^^^^^^^ help: consider using the `From` trait instead: `isize::from(v)` | |
| | |
= note: an `as` expression can only be used to convert between primitive types or to coerce to a specific trait object | |
error: aborting due to previous error | |
