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

--> $DIR/cant-hide-behind-direct-struct-param.rs:10:1

LL | impl PartialEq for NoDerive { fn eq(&self, _: &Self) -> bool { false } }
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
