+error: lifetime may not live long enough

+LL | fn to_longer_lifetime<'r>(b_isize: Invariant<'r>) -> Invariant<'static> {
+ | -- lifetime `'r` defined here
+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
