error: lifetime may not live long enough

--> $DIR/regions-infer-invariance-due-to-mutability-4.rs:10:5

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
