How C++20 Can Simplify std::tuple - Alisdair Meredith [ACCU 2019]
#Cpp #ACCUConf #cpp20
std::tuple has been the source of many presentations over the years, as the library specification glosses over a variety of implementation pitfalls, while successive standards increase the complexity.
C++20 finally provides a number of features that, when combined, can yield a much simpler solution, saving developers of generic wrapper types from layers of expert-only code.
This talk will show how applying the new Concepts language feature, in conjunction with new attributes and some extended syntax, enable the delivery of an optimized high performance implementation that is almost as simple as just declaring a class with a few data members. No metaclasses required!
-------------------------
Alisdair Meredith is a software developer at BloombergLP in New York, and previous chair of the C++ Standard Committee Library Working Group.
He has been an active member of the C++ committee for just over a decade, and by a lucky co-incidence his first meeting was the kick-off meeting for the project that would become C++11, and also fixed the contents of the original library TR.
He is currently working on the BDE project, BloombergLP’s open source libraries that offer a foundation for C++ development, including a standard library implementation supporting the polymorphic allocator model proposed for standardization.
