std::experimental::shared_future<T>::operator=

std::experimental::shared_future<T>& operator=( const std::experimental::shared_future<T>& other );	(1)
std::experimental::shared_future<T>& operator=( std::experimental::shared_future<T>&& other ) noexcept;	(2)

賦值另一個 std::experimental::shared_future 物件的內容。

1) 釋放任何共享狀態，並將 other 的內容賦值給 *this。賦值後，this->valid() == other.valid()。

2) 釋放任何共享狀態，並將 other 的內容移動賦值給 *this。賦值後，other.valid() == false 且 this->valid() 將產生與賦值前 other.valid() 相同的值。
