Move-assign a basic_raw_socket
from a socket of another protocol type.
template< typename Protocol1, typename Executor1> enable_if< is_convertible< Protocol1, Protocol >::value &&is_convertible< Executor1, Executor >::value, basic_raw_socket & >::type operator=( basic_raw_socket< Protocol1, Executor1 > && other);
This assignment operator moves a raw socket from one object to another.
The other basic_raw_socket
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_raw_socket(const executor_type&)
constructor.
