std::optional

[hansaaa]

hi, I have been reading, and, hearing, a fair amount of stuff, on, std::optional /boost::optional.

It seems to be some template class/container, but I can't find it anywhere here, or anywhere else, really.

May someone explain what it is? And/or, its use?

Thanks!

std::optional<> is C++14

Ah, Thanks! I guess, C++14 was the reason, why I hadn't found it, yet.

Thanks!
