##### allocator_binder::allocator_binder (5 of 9 overloads)

Construct a copy of a different allocator wrapper type, but specify a different allocator.

    template<
        typename U,
        typename OtherAllocator>
    allocator_binder(
        const allocator_type & s,
        const allocator_binder< U, OtherAllocator > & other,
        constraint_t< is_constructible< T, U >::value >  = 0);

This constructor is only valid if the type `T` is constructible from type `U`.
