> [C++] 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
> Assignee: Ben Kietzman
> Priority: Major
> Labels: pull-request-available

> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> 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.
