inline function的用法和樣例：
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.
如果是這種情況，你可能會通過將它聲明成內聯函數來避免函數調用的消耗。 - In contrast, when an inlined function is invoked, the compiler inserts the object code for that function at the point-of-call.
相反，當內聯函數被調用的時候，編譯器會把對象源代碼插入到引用函數之處。
辭彙搭配
- in line 成一直線
