For macros that are implemented on the compiler, we do *not* mention the `-Zmacro-backtrace` flag. This includes `derive`s and standard macros.

error: const `impl` for trait `PartialEq` which is not marked with `#[const_trait]`

LL | #[derive_const(PartialEq)]

| ^^^^^^^^^ this trait is not `const`
|
|
|
|

= 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

error: `~const` can only be applied to `#[const_trait]` traits

|
|

note: `PartialEq` can't be used with `~const` because it isn't annotated with `#[const_trait]`
