error[E0605]: non-primitive cast: `NonNullary` as `isize`
--> $DIR/tag-variant-cast-non-nullary.rs:19:15

LL | let val = v as isize;
| ^^^^^^^^^^ an `as` expression can be used to convert enum types to numeric types only if the enum type is unit-only or field-less

help: consider using the `From` trait instead
