+error: lifetime may not live long enough

+LL |     b_isize
+   |     ^^^^^^^ returning this value requires that `'r` must outlive `'static`
+   |
+   = note: requirement occurs because of the type `Invariant<'_>`, which makes the generic argument `'_` invariant
+   = note: the struct `Invariant<'a>` is invariant over the parameter `'a`
+   = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
