warning: this `Deref` implementation is covered by an implicit supertrait coercion

LL | impl<'a> Deref for dyn Foo + 'a {

|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `dyn Foo` implements `Deref<Target = dyn Bar<u32>>` which conflicts with supertrait `Bar<i32>`

...

LL | type Target = dyn Bar<u32> + 'a;

|
| -------------------------------- target type is a supertrait of `dyn Foo`
