      Assigns the contents of anothershared_future.

      1) Releases any shared state and assigns the contents ofother to*this. After the assignment,this->valid()== other.valid().
      2) Releases any shared state and move-assigns the contents ofother to*this. After the assignment,other.valid()==false andthis->valid() will yield the same value asother.valid() before the assignment.

      [edit]Parameters

      other - astd::shared_future that will transfer state to*this

      [edit]Return value

      *this
