What is the <=> ("spaceship", three-way comparison) operator in C++?

On 2017-11-11, the ISO C++ committee adopted Herb Sutter's proposal for the <=> "spaceship" three-way comparison operator as one of the new features that were added to C++20.In the paper titled Consistent comparison Sutter, Maurer and Brown demonstrate the concepts of the new design. For an overview of the proposal, here's an excerpt from the article:

3-way comparison operator (Space Ship Operator) in C++ 20

The three-way comparison operator "<=>" is called a spaceship operator. The spaceship operator determines for two objects A and B whether A < B, A = B, or A > B. The spaceship operator or the compiler can auto-generate it for us. Also, a three-way comparison is a function that will give the entire relationship in one query.

Simplify Your Code With Rocket Science: C++20’s Spaceship Operator

The spaceship operator is a welcomed addition to C++ and it is one of the features that will simplify and help you to write less code, and, sometimes, less is more. So buckle up with C++20’s spaceship operator! We urge you to go out and try the spaceship operator, it’s available right now in Visual Studio 2019 under /std:c++latest!

C++20: More Details to the Spaceship Operator – MC++ BLOG

Let me dive into this post into the details of the spaceship operator. First, I want to add something I should have written about in my first post to the three-way comparison operator: “C++20: The Three-Way Comparision Operator“. Direct Usage of the Three-Way Comparison Operator. You can directly use the spaceship operator:

C++: Overloading the Spaceship Operator, A Recipe

With this defined, operator!= is also implicitly defined, completing the set of six comparison operators. Summary. That’s all. The relational operators can be defined with a single definition of operator<=>.The catch is that the equality operators are not defined by this, so a definition of operator== is still required to complete the set.. Here’s complete source code for further exploration.

C++20: Inside of a spaceship - Andreas Fertig's Blog

This std::operator> takes two arguments, first the result of the spaceship-operator and second an integer to which the result is then compared. All this comes with the new header comparison and a C++20 able compiler. Equality and inequality expressions can now find reversed and rewritten candidates.

Mastering the C++ Spaceship Operator Explained

The C++ spaceship operator, denoted by `<=>`, is a newly introduced feature in C++20 designed to facilitate a simpler and more efficient way of comparing objects. This operator is also known as the "three-way comparison operator," as it returns an indication of whether one object is less than, ...

The Spaceship Operator and Expression Rewriting

In this lesson, we explored the power of C++20's spaceship operator (<=>) and expression rewriting, showcasing how these features make it easier to implement comparison operators for custom types. Key Takeaways. Through the use of these C++20 features, only two primary comparison operators need to be defined (== and <=>).
