问使用指针转换来存储/转换值:我是否违反了严格的混叠规则？

#include <boost/static_assert.hpp>

template <typename T>
struct MyType {

    private:
    T data;

    public:
    template <typename U>
    operator U () {
        BOOST_STATIC_ASSERT_MSG(sizeof(U) == sizeof(T),"Trying to convert to data type of different size");
        return *((U*) &data);
    }

    template <typename U>
    NeonVectorType<T>& operator =(const U& in) {
        BOOST_STATIC_ASSERT_MSG(sizeof(U) == sizeof(T),"Trying to copy from data type of different size");
        data = *((T*) &in);
        return *this;
    }
}
