Compilation error due to handle::clone using incomplete handle type (C++20)

[gix]

handle::clone() returns result<handle>, and using C++20 result requires a complete type due to the is_destructible check in type_can_be_used_in_basic_result. But at this point the handle class is still incomplete.

You surprise me, as I use LLFIO in C++ 20.

Which compiler and standard library? Exact versions please.

[gix]

MSVC 19.24.28314 and clang-cl/clang with a trunk build from last week (clang required fixing the __cpuid lambda in impl/windows/storage_profile.ipp by making the cpuInfo pointer non-const).

Small repro: https://godbolt.org/z/38ijAH

My cmake options are, among others:

-DLLFIO_USE_EXPERIMENTAL_SG14_STATUS_CODE=ON
-DCMAKE_CXX_STANDARD=20

Ok, should be fixed now. If your LLFIO is using Outcome via superbuild into your build directory, you will need to remove the outcome subdirectory within your build directory, and rerun cmake.
