It makes perfect sense actually. I did write another comment here if you are interested.
This is how operator overloads were written going back to the initial version of C++ back in 1985. The only new thing is that we can now add = default to get the compiler to generate a default implementation that compares all the member variables for you.
Maybe to a non C++ dev, but a lot of C++ is probably incomprehensible to a non C++ dev, just like there are other laguages that are incomprehensible to C++ devs. To me it makes perfect sense as it works just like all the other operator overloads.
auto - let the compiler deduce return type
operator<=> - override the spaceship operator (pretty sure it exists in python too)
(const ClassName&) - compare this class, presumably defined in Class name, with a const reference of type Class name, i.e. its own type.
const - comparison can be made for const objects
= default; - Use the default implementation, which is comparing all the member variables.
An alternate more explicit version, which is actually what people recommend:
auto operator<=>(const ClassName&, const ClassName&) = default;
if I just want to have less than comparison for example I would:
This one makes it explicit that you’re comparing two Class name objects.
if I just want to have less than comparison for example I would:
auto operator<(const ClassName&, const ClassName&) = default;
If I need to compare against another class I could define:
auto operator<(const ClassName&, const OtherClass&)
You mean copy/move constructor and assignment operator?
Unless you have any special handling the ones generated by the compiler automatically should work just fine. But if you do have to define them for some reason (which is becoming increasingly rare) you would need to define both if you need both copy/move construction and copy/move assignment.
I do appreciate how newer C++ standards have made these kinds of things a lot easier too.
Define all comparison operators with just one one line using C++20
auto operator<=>(const ClassName&) const = default;
Not to defend them too much and I have to admit that I don’t know much about the details which bills were priorities during the 4 months that Obama has house, senate and Presidency.
What I did read a while back was that Obama didn’t know how long his supermajority would last and some of the things he wanted he wanted done but couldn’t once he lost the house.
Nope, not a valid reason.
The constitution was made to be amended to adapt with the times. Time to amend the 2nd amendment and require a valid reason such as hunting for having a firearm.
I stand corrected, and I see I didn’t read the comment thoroughly enough either.
Colloquially as a non-pcb maker I would use and hear the term “mill” as short form millimeter so I assumed it was that.
so TIL :)
A millimeter i.e a thousands of a meter.
edit: I was wrong, confusingly enough it is a thousands of an inch
Thai Airways by any chance? I kept getting weird errors in ff but was ok I’m chrome.
Very possible and even probable that they’re using some chrome specific behaviour. Just like back in late 90s early noughts when so many websites were IE specific making is impossible to use without a windows installation. The effect is though that unfortunately Firefox isn’t usable everywhere. Sometimes you need chrome for some specific websites. This is especially true for some self hosted “enterprise” web apps, I need chrome for one of those too.
I use Firefox on Linux and FreeBSD for my daily driver.
I was not able to book flights on Thai airways website 6 months ago until I loaded it in chrome/chromium instead.
It’s really really rare imo but that’s one example in recent history.
I’m not sure it’s just right leaning users. I’m pretty far to the left and I keep ketting anti-trans, anti-covid right wing talking points quite frequently. I keep pressing thumbs down but they keep coming.
I tried to look this up but I couldn’t find much. The “worst” I found was this:
Where are you reading that people are saying that it’s worse than twitter? Is it right wing people that are saying that because they put emphasis on inclusivity and respect?
