error: opaque type used twice with different lifetimes

LL |     (i, j)
   |     ^^^^^^

   |     lifetime `'x` used here
   |     lifetime `'y` previously used here

note: if all non-lifetime generic parameters are the same, but the lifetime parameters differ, it is not possible to differentiate the opaque types
