It is better to put those struct's functions in header file, and remove this
file?

According to chromium code style, we shouldn't inline constructors.

But it still looks not much reasonable for me, to add a .cc file for a such
simple struct. Maybe you should use class instead of struct to emphasize this is
not a struct, it has some member functions.

Just removed it. We actually don't need it.
