inline function的用法和样例：
例句
- If that is the case, you'll probably be tempted to avoid paying the overhead cost of a call to an empty function by declaring your destructor inline.
如果是这种情况，你可能会通过将它声明成内联函数来避免函数调用的消耗。 - In contrast, when an inlined function is invoked, the compiler inserts the object code for that function at the point-of-call.
相反，当内联函数被调用的时候，编译器会把对象源代码插入到引用函数之处。
词汇搭配
- in line 成一直线
