error: lifetime may not live long enough

help: to declare that the trait object captures data from argument `ss`, you can add an explicit `'_` lifetime bound

error[E0507]: cannot move out of `ss.r` which is behind a mutable reference

LL | ss.r
| ^^^^ move occurs because `ss.r` has type `Box<dyn SomeTrait>`, which does not implement the `Copy` trait
error[E0621]: explicit lifetime required in the type of `ss`
