Structs and constructors

Today, we are going to talk about when and why structs should have constructors if they should have them at all. We are also going to see once again that generic best practices and best practices to reduce binary size do not always go hand in hand.

I didn’t like this code. Even though the struct didn’t have any constructors, even though not all the members were set, with the help of designated initializers it’s so easy to get rid of the initialize then modify anti-pattern Connor Hoekstra talked about a couple of years ago at the Italian C++ conference.

As a result, you get code that still tells you what is initialized, code which is more efficient without making it less readable and in addition you don’t have to think about why the object is created before its members are set.

Next, I checked some code where I did see some non-default constructors, probably because people wanted to avoid to previous pattern.
