| --> $DIR/issue-26905.rs:26:40 |

| LL | impl<T: ?Sized + Unsize<U>, U: ?Sized> CoerceUnsized<MyRc<U>> for MyRc<T>{ } //~ERROR |
| | ^^^^^^^^^^^^^^^^^^^^^^ requires multiple coercions |
| | |
| = note: `CoerceUnsized` may only be implemented for a coercion between structures with one field being coerced |
| = note: currently, 2 fields need coercions: _ptr (*const T to *const U), _boo (NotPhantomData<T> to NotPhantomData<U>) |
| |
| error: aborting due to previous error |
