Welcome to new C++ Links - most important and useful articles, podcasts and videos that happen between 6th and 12th of April 2019.
In this week you will find the link to post about co_awaiting coroutines, link to an article how to write spaceship operator with std::tuple & CRTP pattern and many more!
Guest post on the fluentcpp blog - from Henrik Sjöström. He is showing how to implement the Spaceship operator before C++20. To implement it he uses… tuples in combination with Curiously Recurring Template Pattern:
fluentcpp.com/2019/04/09/how-to-emulate-the-spaceship-operator-before-c20-with-crtp/Article about coroutines from Dawid Pilarski - he describes Awaitable and Awaiter concept, co_await operator and await_transform. A little bit magic inside, but after reading it you should be able to implement any coroutine
