Operators and Conventional Operations
The handful of operations that make a type feel built in. Why operator+ should be a free function, how one defaulted <=> gives all six comparisons, why == is still worth writing separately, swap as three moves, hashing our own type for unordered containers, and user-defined literals.
You will learn
- Choose between member and free (symmetric) operators
- Use a defaulted <=> and explain why a fast == is written separately
- Explain std::swap as three moves
- Specialize std::hash and write a user-defined literal
