It depends on the structure of your code and on what you do exactly.
For example, if you've got a chain "send-handler-send-...", and you
use shared_from_this idiom, and this chain ends at some stage of your
program -- you shouldn't do anything more, as your connection object
along with its socket will destroy & close automatically, thanks to
the shared_from_this idiom.
OTOH, if your chain is "infinite", eg. it's a receiving socket, which
should always be listening for incoming data -- then you should close
it explicitly by calling socket.close().

It means that the connection has been closed.
