https://cppcon.org​ --- Back to Basics: Lifetime Management in Cpp - Phil Nash - CppCon 2024 --- Lifetime management in C++ is flexible and powerful. But this comes with complexity and lots of ways to shoot your leg off. That has only gotten worse as the language has evolved. This talk introduces or recaps the so-called Rule of 0 and Rule of 5, which suggest that you should aim to need no Special Member Functions (customs constructors, destructors assignment operators) for most of your types. But if you do need them, you probably need all 5. But if we do need to implement them it can still be hard to know what to do. It helps to know what sort of type you are dealing with, so we’ll break down the common categories. Along the way we’ll look at vocabulary types we already have in the C++ standard library that can help us move more of our code into the realm of the Rule of 0. Come with us on a journey through these rules, type categories and behaviours and start to make sense of lifetimes in modern C++. --- Slides: https://github.com/CppCon/CppCon2024/blob/main/Presentations/Back_to_Basics_Lifetime_Management.pdf Sponsored by JetBrains: https://www.jetbrains.com/clion/ --- Phil Nash Phil is the original author of the C++ test framework, Catch2. He's an independent trainer and consultant. He's also a member of the ISO C++ standards committee, organiser of C++ London and C++ on Sea, as well as co-host and producer of CppCast. More generally he's an advocate for good testing practices, TDD and using the type system and functional techniques to reduce complexity and increase correctness. He's previously worked in Finance and Mobile offers training and coaching in C++ and TDD. --- CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
