suggest broken template code

Code

pub type AM<T> = Arc<Mutex<T>>;
pub trait ArcMutexTrait<T> {
    fn n(t: T) -> AM<T> { Arc::new(Mutex::new(t)) }
    fn get(&self) -> T { self.clone().lock().unwrap() }
}
impl<T> ArcMutexTrait<T> for AM<T> {}

Current output

error[E0599]: no method named `lock` found for reference `&Self` in the current scope

No response

Start by reproducing the Rust snippet with rustc 1.84.0 and inspect the compiler's suggested fix for the missing lock method. Determine what compilable suggestion is expected; done means the diagnostic no longer recommends invalid template code.
