regarded and expertly designed C++ library projects in the
world.

This is an older version of Boost and was released in 2015. The current version is 1.89.0.
Run the io_service object's event processing
loop to execute at most one handler.
std::size_t run_one();
The run_one()
function blocks until one handler has been dispatched, or until the
io_service
has been stopped.
The number of handlers that were executed. A zero return value implies
that the io_service object is stopped
(the stopped()
function returns true).
Subsequent calls to run(), run_one(), poll() or poll_one() will return immediately unless there
is a prior call to reset().
Thrown on failure.
