error[E0308]: mismatched types

LL | fn bar_function<T>(function: Foo<T>) -> RcFoo<T> {
| ------------ ^^^^^^^^ expected `Rc<&dyn Fn(&T)>`, found `()`
| |
| implicitly returns `()` as its body has no tail or `return` expression
|
= note: expected struct `Rc<&dyn for<'a> Fn(&'a T)>`
found unit type `()`
help: consider returning the local binding `rc`

LL ~ let rc = Rc::new(function);
LL + rc
