Since we're using C++20 now, constructors for "trivial" data classes can be omitted using designated initializers, e.g.
PathInfoCacheValue { .value = some_value }
and time_point could have a default initializer:
std::chrono::time_point<std::chrono::steady_clock> time_point = std::chrono::steady_clock::now();

Hm, removing the return looks potentially wrong...

Yes it was. The compiler was complaining about return in a void function. I've re-added the return and then it works.

Ready for review. I'll make a PR with the previous variation for a 2.3 backport. |
