Anders Wind created ARROW-13444:
-----------------------------------
Summary: C++20 compatibility by updating std::result_of to
std::invoke_result
Key: ARROW-13444
URL: https://issues.apache.org/jira/browse/ARROW-13444
Project: Apache Arrow
Issue Type: Wish
Components: C++
Affects Versions: 4.0.1
Reporter: Anders Wind
There are currently 5 header files which uses {{std::result_of}}. As specified
here [https://en.cppreference.com/w/cpp/types/result_of,] {{std::result_of}}
got deprecated in c++17 and removed in c++20. Because of this, its not possible
to include the c++ arrow headers in a project using c++20 without getting
compilation errors.
To solve this, cppreference specifies how {{std::invoke_result}} can be used
instead of {{std::result_of}}. Unfortunately {{std::invoke_result}} was only
added in c++17 and therefore I expect that solving this will require some macro
work, to keep c++14 and lower support.
This is the first time I post an issue and I hope I have followed the rules.
