| error: constant of non-structural type `NoDerive` in a pattern |
| --> $DIR/cant-hide-behind-direct-struct-param.rs:21:9 |
| | |
| LL | struct NoDerive(i32); |
| | --------------- `NoDerive` must be annotated with `#[derive(PartialEq)]` to be usable in patterns |
| ... |
| LL | const WRAP_DIRECT_PARAM: WrapParam<NoDerive> = WrapParam(NoDerive(0)); |
| | -------------------------------------------- constant defined here |
| ... |
| LL | WRAP_DIRECT_PARAM => { panic!("WRAP_DIRECT_PARAM matched itself"); } |
| | ^^^^^^^^^^^^^^^^^ constant of non-structural type |
| | |
| note: the `PartialEq` trait must be derived, manual `impl`s are not sufficient; see https://doc.rust-lang.org/stable/std/marker/trait.StructuralPartialEq.html for details |
