standalone version of folly::Synchronized

Question

Is there a functional equivalent of https://github.com/facebook/folly/blob/main/folly/docs/Synchronized.md that is self-contained and preferably header only so I don't have to pull in entire folly library into my project?

Answer 1

There is a dicussion on reddit where folly::Synchronized also has been mentioned and some other solutions are provided.

Probably you're searching for something like this: https://github.com/copperspice/cs_libguarded

A snippet of there test code:

shared_guarded<int, shared_mutex> data(0);
{
   auto data_handle = data.lock();
   
   ++(*data_handle);
   
   data_handle.reset();
   data_handle = data.lock();
}

auto data_handle = data.try_lock();
      
REQUIRE(data_handle != nullptr);
REQUIRE(*data_handle == 1);

Note: cs_libguarded requires C++17.
