LL | pub fn foo<'a, 'b>(u: &'b ()) -> &'a () {
   |            --  -- lifetime `'b` defined here
   |            |
   |            lifetime `'a` defined here
LL |     Foo::xmute(u)
   |     ^^^^^^^^^^^^^ function was supposed to return data with lifetime `'a` but it is returning data with lifetime `'b`

   = help: consider adding the following bound: `'b: 'a`

error: aborting due to previous error
