error: lifetime may not live long enough
|
|
--> $DIR/regions-variance-invariant-use-covariant.rs:17:12
|
|

|
|
LL | fn use_<'b>(c: Invariant<'b>) {
|
|
| -- lifetime `'b` defined here
|
|
...
|
|
LL | let _: Invariant<'static> = c;
|
|
| ^^^^^^^^^^^^^^^^^^ type annotation requires that `'b` 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
