Back to Basics: Algebraic Data Types I also do C++ training! arthur.j.odwyer@gmail.com Arthur O’Dwyer 2020-09-16Outline ● Why the name “algebraic data types”? [3–18] ○ Memory layout diagrams. Why Questions? 2What do I mean by algebraic types? pair C++98. The original algebraic data type. tuple C++11. optional C++17. variant C++17, with minor tweaks to its constructors The memory layout of pair or tuple is going to be pretty much the same as the layout of a plain old data struct. pair tuple 6 A The compiler will do some padding for alignment, and may
