Three-way comparison operator
Hi Boosters, Does anyone know if Boost.Test has been updated to provide support for the three-way comparison operator? I’m asking because I’ve encountered a situation where my user-defined class provides the three-way comparison operator but when I perform comparisons using Boost.Test it complains that my class has no ‘operator==’ which is true because it provides ‘operator<=>’. Please note that I’m using Boost 1.73.0 and g++ 10.0.1. Is there any plan to add the three-way comparison operator support? Kind regards, Leo

Scanning the change log it doesn't seem likely boost.test was updated. Also given that the feature really just arrived in clang 10 in the last month and gcc 10 isn't yet released almost no one has reacted to operator<=> yet. All that said, most stuff like boost.test that uses operators shouldn't need to be modified. A deeper possibility here is boost.test is fine and that Leo might need to implement operator== with the operator<=>. Have a look thru this blog post https://brevzin.github.io/c++/2019/07/28/comparisons-cpp20/ https://www.boost.org/doc/libs/1_73_0/libs/test/doc/html/boost_test/change_l...

One of the changes of C++20, coming with operator<=>, is rewritten candidates for comparison operator overload resolution, which has been causing massive breakage among any significant C++ codebase. Many people have already been submitting patches for these for the last six months in various software packages, Boost included.
