std::future

future::future

future::~future

future::operator=

future::share

获取结果

future::get

状态

future::valid

future::wait

future::wait_for

future::wait_until

 

future& operator=( future&& other ) noexcept;	(1)	(C++11 起)
future& operator=( const future& other ) = delete;	(2)	(C++11 起)

赋值另一 future 对象的内容。

1) 释放任何共享状态并移动赋值 other 的内容给 *this 。赋值后， other.valid() == false 且 this->valid() 将产生与 other.valid() 在赋值前相同的值。

2) std::future 不可复制赋值 (CopyAssignable) 。

参数

other

-

将转移状态给 *this 的 std::future

返回值

*this
