Bind move-only structure to function

I need to bind structure with deleted copy-constructor to a function. I have reduced what I am trying to achieve into following minimal example:

struct Bar {
    int i;
    Bar() = default;
    Bar(Bar&&) = default;
    Bar(const Bar&) = delete;
    Bar& operator=(const Bar&) = delete;
};

void foo(Bar b) {
    std::cout << b.i << std::endl;
}

int main()
{
    Bar b;
    b.i = 10;

    std::function<void()> a = std::bind(foo, std::move(b)); // ERROR
    a();

    return 0;
}

From the compiler I get only wailing and gnashing of teeth:

test.cpp:22:27: error: no viable conversion from 'typename _Bind_helper<__is_socketlike<void (&)(Bar)>::value, void (&)(Bar), Bar>::type' (aka '_Bind<__func_type (typename decay<Bar>::type)>') to 'std::function<void ()>'
    std::function<void()> a = std::bind(foo, std::move(b));

So I would like to ask whether there is any workaround that would allow me to bind Bar to foo while keeping Bar move-only.
