The compiler-generated function can be more efficient. 使用类内初始化器可以让编译器为你生成一个函数。编译器生成的函数效率更高。 // ... }; Example(示例) class X2 { string s = "default"; int i = 1; public: // use compiler-generated

Moderate) The body of a special operation should not have the same accessibility and semantics as the compiler-generated
fails to compile, or does something suspicious If you define a destructor, you should not use the compiler-generated Prefer compiler-generated (including =default) special members; only these can be classified as "trivial
Note(注意) A destructor (either user-defined or compiler-generated) is implicitly declared noexcept (independently

事件侦听器缓存 等等 4, 更多编译时优化 Slot 默认编译为函数:父子之间不存在强耦合,提升性能 Monomorphic vnode factory:参数一致化,给它children信息, Compiler-generated
如果不想使用compiler-generated functions编译器生成函数,就明确拒绝 7. 如果不想使用compiler-generated functions编译器生成函数,就明确拒绝 为了拒绝编译器生成函数,将相应的 member functions(成员函数)声明为 private,而且不要给出
地址码中的地址可能有如下的几种类型:名字(Name),包括变量(Variable)标签(Label)用于指示程序位置,方便跳转指令的书写字面常量(Literal Constant)编译器生成的临时量(Compiler-Generated

针对上面的协程some_coroutine,以及它的返回值类型T,调用协程的语句可以理解为如下过程 (引自参考文献1) // Pretend there's a compiler-generated structure
这里会用到一个Data类型,也是完全copy的dyno的实现,定义如下: struct Data { Data() = default; // Suppress compiler-generated
传统基于 C# 编译器的 async/await 实现依赖于生成复杂的托管状态机(Compiler-generated state machine),而.NET 11 的 Runtime Async 将这些协程挂起
