Enhancing Safety in C++ Code With Modern C++ Quantities and Units Library - Mateusz Pusz - ACCU 2024
---
Safety has been a huge buzzword in the C++ Community in recent years. There are many concerns about the safety of our C++ language, and projects developed using it. Many improvements are being discussed, starting from handling of the low-level fundamental types, through updating the language rules (e.g., initialization), up to providing safer high-level abstractions in the library.
This lecture presents how the usage of a Modern C++ quantities and units library can improve the safety of the code we write every day. During the talk, Mateusz will describe all issues and possible solutions discussed in [P2981: Improving our safety with a physical quantities and units library](wg21.link/p2981). Based on the examples developed with the mp-units project, the attendees will not only learn the obvious benefits of using such a library, but also some less known safety features will be presented.
During the talk, we will see typical issues of code bases that do not use a proper library. We will also learn about various mishaps in engineering that happened through the ages and were caused by human errors in handling quantities and their units. We will also see how they can be easily and safely addressed using the mp-units library.
In the end, Mateusz will describe which issues can't be solved by the quantities and units library itself for now. He will review a list of potential extensions to the C++ language and its library that would allow even more safety in our projects.

The ACCU Conference is the annual conference of the ACCU membership, but is open to any and all who wish to attend. The tagline for the ACCU is 'Professionalism in Programming', which captures the whole spectrum of programming languages, tools, techniques and processes involved in advancing our craft. While there remains a core of C and C++ - with many members participating in respective ISO standards bodies - the conference, like the organisation, embraces other language ecosystems and you should expect to see sessions on C#, D, F#, Go, Javascript, Haskell, Java, Kotlin, Lisp, Python, Ruby, Rust, Swift and more.The ACCU Conference is a conference by programmers for programmers about programming.
Discounted rates for members.

I love the U++ icon :D
I would prefer a prefix for public data members like "__private_" or "__internal_" . The postfix seems strange to me... but yeah not that important.
I am happy that you like the icon. It took us a lot of time and iterations to come up with it 🙂
Regarding the prefix for public data members, it is just an implementation detail that I may change before every library release. 😈
Two underscores are reserved in the language, and its usage outside the `std` namespace is an undefined behavior, so I would not like to use it in mp-units.
force_in() should be forced_into()
4:13 Roth Michael’s talk from cppcon about strong types for audio: ruclips.net/video/oxnCdIfC4Z4/видео.html
Roth's talk is really nice indeed. I helped him design those types for his use case, and we were very happy with the final result.
So excited for C++ standard units 🤩
It is great to hear that! Thanks!
