error[E0195]: lifetime parameters or bounds on method `get` do not match the trait declaration

LL |     fn get<'p, T : Test<'p>>(&self) -> T;
   |           ------------------ lifetimes in impl do not match this method in trait
...

   |           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ lifetimes do not match method in trait

error[E0605]: non-primitive cast: `Foo<'a>` as `T`
  --> $DIR/issue-16048.rs:24:16
   |
LL |         return *self as T;
   |                ^^^^^^^^^^ help: consider using the `From` trait instead: `T::from(*self)`

   = note: an `as` expression can only be used to convert between primitive types or to coerce to a specific trait object
