在https://doc.rust-lang.org/book/ch04-02-references-and-borrowing.html中,我发现了使用String类型引用的非常相似的示例,但在我的代码中,我得到了move occurs because `*paths_ref` has type `ReadDir`, which does not implement the `Copy` trait。如何在没有memcopy的情况下使用R
据我所知,引用是一种指针类型,当取消引用时,它会将您带到内存中的某个值。let y = &xlet y = &x;// fails to compile as move occurs because `*y` hastype `Point`, which does not implement the `Co
动机:在 std::move_only_function的实现中,我想为从move_only_function<int() noexcept>到move_only_function<int()>的转换编写一个不分配的特例::move(f); // should just copy the bitsif constexpr (is_noexcept_version_of<HisSignature, MySignature
