std::move_iterator是一种迭代器适配器,表现与它的底层迭代器(必须至少是一个老式输入迭代器(LegacyInputIterator)或实现input_iterator(C++20 起))严格相同,但解引用会将底层迭代器返回的值转换为右值。如果此迭代器用作输入迭代器,那么效果是值被移动,而非复制。

a function call or an overloaded operator expression of rvalue reference to object return type, such as std::move(x); (注意:返回右值引用的表达式(方法和运算符重载),是消亡值,而不是纯右值) a[n], the built-in subscript expression, where one operand is an array rvalue ; ...
1) 把右值引用类型作为返回的函数或者重载操作符。例如, std::move(x); 2) a[n], 内置的下标[subscript]表达式,其中,‘a’是一个右值数组。 3) a.m, 对象的取成员变量表达式。其中,‘a’是一个右值,‘m’ 是非引用类型的非静态数据成员。
