error: const `impl` for trait `PartialEq` which is not marked with `#[const_trait]`
--> $DIR/derive-const-with-params.rs:6:16

LL | #[derive_const(PartialEq)]
| ^^^^^^^^^

= note: marking a trait with `#[const_trait]` ensures all default method bodies are `const`
= note: adding a non-const method body in the future would be a breaking change
= note: this error originates in the derive macro `PartialEq` (in Nightly builds, run with -Z macro-backtrace for more info)
error: ~const can only be applied to `#[const_trait]` traits
