error[E0631]: type mismatch in closure arguments

= note: expected closure signature `fn(_) -> _`
found closure signature `fn(&_) -> _`
note: closure inferred to have a different signature due to this bound

LL | fn foo<F: Fn(&char) -> bool + Fn(char) -> bool>(f: F) {
| ^^^^^^^^^^^^^^^^^
note: required by a bound in `foo`

LL | fn foo<F: Fn(&char) -> bool + Fn(char) -> bool>(f: F) {
| ^^^^^^^^^^^^^^^^ required by this bound in `foo`
help: consider adjusting the signature so it does not borrow its argument

LL | foo(move |char| v);
