[Boost.Asio] Can I move io_context away while having sockets bound to it?
You created serveral sockets and bound them to an io_context Is it safe to std::move the io_context away? Will those sockets be affected, or even be invalidated?

It's not a matter of safety. It's just impossible, an io_context is not movable (or copyable): https://www.boost.org/doc/libs/1_78_0/doc/html/boost_asio/reference/io_conte...

As a side note, if you want something moveable, use the io_context's executor. It is both moveable and cheaply copyable. Amongst other things, it acts as a handle to the underlying io_context.
