Where does the standard specify that functions defined inside a class are inline?

Question

In my understanding, member functions defined inside a class definition are implicitly inline:

class X {
  int f() { return 1; } // Implicitly inline.
};
int g() { return 2; } // Not implicitly inline.

I was looking for the standard quote to support this, but I can only find basic.link/7:

In addition, a member function, static data member, a named class or enumeration of class scope, or an unnamed class or enumeration defined in a class-scope typedef declaration such that the class or enumeration has the typedef name for linkage purposes ([dcl.typedef]), has the same linkage, if any, as the name of the class of which it is a member.

I can't find anything relevant in dcl.typedef that relates to simple class definitions (without typedef being involved).

我在找对地方了吗？如果不是，确切的标准措辞在哪里？

Answer 1

也许在有关的部分中查找inline。

[dcl.inline]/4: 在类定义中定义的函数是内联函数。

实际上，稍后会在有关成员函数的部分中重复上述操作（这似乎也很明智！）：

[class.mfct]/1:成员函数可以在其类定义中定义，在这种情况下，它是内联成员函数[..]
