C++ 20 (2a) New Features - Associated Changes in Operator==

The video tutorial discusses changes in the equality operator, focusing on the performance issues of the default spaceship operator. It explains the need to implement a custom equality operator when using a custom spaceship operator. The tutorial demonstrates code execution and highlights that defaulted spaceship operators generate additional comparison operators. It concludes with a note on standard library types and introduces the next topic.

How does the performance of the equality operator compare to the standard three-way comparison operator for certain types?

What is a caveat regarding standard library types and the three-way comparison operator?
