ExecutorIn-process concurrency infrastructure for C++20 applications

At a glance ​

auto& executor = executor::Executor::instance();
auto answer = executor.submit_auto([] { return 42; });
std::cout << answer.get() << '\n';
executor.shutdown();

get() both retrieves the result and rethrows an exception from the task. See your first task for complete code and expected output.

Scope and boundaries ​

Executor is not a coroutine runtime, a distributed messaging system, or a hard realtime OS. It cannot safely force arbitrary running C++ functions to terminate, and submit_periodic() is soft periodic work on the ordinary pool, not a dedicated realtime thread. See what is Executor? for the complete boundary statement, including the synchronization guarantees introduced in 0.4.0.
