The chops::periodic_timer calls a user supplied callback function at a user defined interval. The callback funtion is repeatedly called while it returns true, but the timer terminates when the function returns false.

The timer executes inside an std::thread. The thread and timer are linked with an asio::io_context. As the example shows, multiple timers can be run inside one thread. An asio::executor_work_guard controls ownership of executor work within the thread. Without either the thread or the exector_work_guard, the timer will not execute.
