Using Boost Asio for Modern Async IO

Use Boost.Asio for portable, modern asynchronous I/O.

Boost.Asio

Boost.Asio is the de facto C++ async I/O library. Cross-platform, header-only-ish, used in production by countless services.

Asio centers on boost::asio::io_context — the event loop. All async operations run on it.

#include <boost/asio.hpp>
namespace asio = boost::asio;

asio::io_context io;
// register async operations...
io.run();
