The Many Shades of reference_wrapper - Zhihao Yuan - CppCon 2020

https://cppcon.org/ https://github.com/CppCon/CppCon2020/... --- You may have heard of std::reference_wrapper's role in make_tuple, but this is not today's topic. The role that reference_wrapper plays is larger than unwrapping references in C++ standard library API. It is the language's response to the need for references with rebinding semantics, which may explain why such a small utility is still receiving love and polishes in C++20. To put it in the other way, every reference in Python is rebindable -- with garbage collection, of course. But the semantics in common implies that reference_wrapper may be very useful. This talk will go through these use cases, see how reference_wrapper's design carefully enables them through details. The talk will also compare reference_wrapper with other facilities in the language and the standard library to give you hints about how to choose from the reference-like types. --- Zhihao Yuan is an HPC Engineer at SimpleRose Inc. He participated in standardizing designated initializers and improved narrowing conversions in C++20. After giving a talk on CppCon to advocate NOT to program any macros, he dived into a project where the number of identifiers that are macros exceeds the number of identifiers that are not. His favorite game series on PS4 is Utawarerumono. --- Work at Hudson River Trading (HRT): https://tinyurl.com/safxfctf --- Streamed & Edited by Digital Medium Ltd - events.digital-medium.co.ukevents@digital-medium.co.uk *-----* Register Now For CppCon 2022: https://cppcon.org/registration/ *-----*
