Move-assign a basic_socket_acceptor
from an
acceptor of another protocol type.
template< typename Protocol1, typename SocketAcceptorService1> enable_if< is_convertible< Protocol1, Protocol >::value, basic_socket_acceptor >::type & operator=( basic_socket_acceptor< Protocol1, SocketAcceptorService1 > && other);
This assignment operator moves an acceptor from one object to another.
The other basic_socket_acceptor
object from which the move will occur.
Following the move, the moved-from object is in the same state as if
constructed using the basic_socket(io_service&) constructor
.
