Description

opened on Jun 2, 2025

The code is generated by a fuzzer and reduced manually
I have tried to minimize the code, but unfortunately it is still too large.

Code

use std::marker::PhantomData;
trait MyTrait {
    fn virtualize(&self) -> &dyn MyTrait;
}
struct VirtualWrapper<T, const L: u8>((T, T));
impl<T, const L: u8> VirtualWrapper<T, L> {
    pub fn wrap(value: &T) -> &Self {
        unsafe { &*(value as *const T as *const Self) }
    }
}
impl<T: MyTrait + 'static, const L: u8> MyTrait for VirtualWrapper<T, L> {
    fn virtualize(&self) -> &dyn MyTrait {
        unsafe { virtualize_my_trait(L, self) }
    }
}
const unsafe fn virtualize_my_trait<T>(level: u8, obj: &T) -> &dyn MyTrait
where
    T: MyTrait + 'static,
{
    const fn gen_vtable_ptr<T, const L: u8>() -> *const ()
    where
        T: MyTrait + 'static,
    {
        let [_, vtable] = unsafe {
            std::mem::transmute::<*const dyn MyTrait, [*const (); 2]>(std::ptr::null::<
                VirtualWrapper<T, L>,
            >())
        };
        vtable
    }
    struct Vtable<T>(PhantomData<T>);
    impl<T> Vtable<T>
    where
        T: MyTrait + 'static,
    {
        const LEVELS: [*const (); 2] = [gen_vtable_ptr::<T, 1>(), gen_vtable_ptr::<T, 2>()];
    }
    let vtable = Vtable::<T>::LEVELS[(level != 0) as usize];
    let data = obj as *const T as *const ();
    let ptr: *const dyn MyTrait = std::mem::transmute([data, vtable]);
    &*ptr
}
struct SomeData<const N: usize>([u8; N]);
impl<const N: usize> MyTrait for SomeData<N> {
    fn virtualize(&self) -> &dyn MyTrait {
        VirtualWrapper::<Self, 0>::wrap(self)
    }
}
fn main() {
    let test = SomeData([0; 256]);
