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!

Comparison operators - cppreference.com

The comparison is deprecated if both lhs and rhs have array type prior to the application of these conversions. (since C++20) (until C++26) For built-in relational operators, if one of the operands is a pointer, the array-to-pointer conversion is performed on the other operand.. For built-in equality operators, if one of the operands is a pointer or a null pointer constant, the array-to ...

C++20: The Three-Way Comparison Operator – MC++ BLOG

The spaceship operator determines whether A < B, A = B, or A > B for two values, A and B. You can define the spaceship operator, or the compiler can auto-generate it. Let me start classically to appreciate the three-way comparison operator’s advantages. Ordering before C++20.

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.

Spaceship operator <=> in C++ - OpenGenus IQ

The three-way comparison operator <=>, colloquially called the spaceship operator was added in C++20. Comparison. Comparison is one of the most commonly used operations in a program. Comparing the built-in types like int's is defined by the language. However, comparison of user-defined types is provided by means of operator overloading.

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 <=>).
