Move-assign a ip::basic_resolver
from another.
basic_resolver & operator=( basic_resolver && other);
This assignment operator moves a resolver from one object to another. Cancels any outstanding asynchronous operations associated with the target object.
The other ip::basic_resolver
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_resolver(const executor_type&)
constructor.
