Introduction
An std::barrier is similar to a std::latch.
There are two differences between a std::latch and a std::barrier. First, you can use a std::barrier more than once, and second, you can set the counter for the next step (iteration). Immediately after the counter becomes zero, the so-called completion step starts. In this completion step, a callable is invoked. The std::barrier gets its callable in its constructor.
The completion step ...
