error: constant of non-structural type `NoDerive` in a pattern
--> $DIR/cant-hide-behind-doubly-indirect-param.rs:22:9
|
LL | struct NoDerive(#[allow(dead_code)] i32);
| --------------- `NoDerive` must be annotated with `#[derive(PartialEq)]` to be usable in patterns
...
LL | const WRAP_DOUBLY_INDIRECT_PARAM: & &WrapParam<NoDerive> = & &WrapParam(& & NoDerive(0));
| -------------------------------------------------------- constant defined here
...
LL | WRAP_DOUBLY_INDIRECT_PARAM => { panic!("WRAP_DOUBLY_INDIRECT_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-doubly-indirect-param.rs:11:1
|
LL | impl PartialEq for NoDerive { fn eq(&self, _: &Self) -> bool { false } }
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
error: aborting due to 1 previous error
