will suppress the implicit declaration of a move constructor and move assignment operator. Declaring a move constructor or move assignment operator, even as=default or =delete, will cause an implicitly generated copy constructor or implicitly generated copy assignment operator to be defined as...

Move constructor and move assignment operator The most common pattern you'll see when working with rvalue references is to create a move constructor and move assignment operator (which follows the same principles). A move constructor, like a copy constructor, takes an instance of an object as ...
有些clang-tidy检查提供了特定的检查方式来消除诊断,比如bugpron-use-after-move后的变量可以通过在变量被移出后重新初始化来消除警告,bugpron-string-integer-assignment可以通过显式转换将整数转换为char来抑制,可读性-implicit-bool-conversion也可以通过显式转换来抑制等等。
