I was trying to go through the boost optional documentation, and I find this with all of the boost docs in that I can't find a clear API definition. I want to determine:
operator& defined and if it checks for validity of the object?0
There are multiple ways, see e.g.:
Note that recently a powerful search box is added that searches all library code and documentation.
Note that the addressof-operator couldn't be safely overloaded in portable code (although given alignment restrictions and [[no_unique_address]] in C++20 might change the equation?).
