Emit more specific diagnostics when enums fail to cast with `as` Fixes #120756 Changes this diagnostic reported in the issue: ``` error[E0605]: non-primitive cast: `Bad` as `u32` --> src/main.rs:18:10 | 18 | dbg!(bad as u32); | ^^^^^^^^^^ an `as` expression can only be used to convert between primitive types or to coerce to a specific trait object ``` to this: ``` error[E0605]: non-primitive cast: `Bad` as `u32` --> src/main.rs:18:10 | 18 | dbg!(bad as u32); | ^^^^^^^^^^ an `as` expression can be used to convert enum types to numeric types only if the enum type is unit-only or field-less | = note: see https://doc.rust-lang.org/reference/items/enumerations.html#casting for more information ``` This change is only for enums. The diagnostic remains unchanged for all other cases. |
