error: lifetime may not live long enough

   |         ^^^^^^^^^^^^^^^^^ argument requires that `'a` must outlive `'tcx`
   |
   = help: consider adding the following bound: `'a: 'tcx`
   = note: requirement occurs because of the type `FnCtxt<'_, '_>`, which makes the generic argument `'_` invariant
   = note: the struct `FnCtxt<'a, 'tcx>` is invariant over the parameter `'tcx`
   = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
