Helper Classes

uses_allocator<std::promise>

 

promise& operator=( promise&& other ) noexcept;	(1)	(since C++11)
promise& operator=( const promise& rhs ) = delete;	(2)	(since C++11)

Assigns the contents.

1) Move assignment operator. First, abandons the shared state (as in ~promise()), then assigns the shared state of other as if by executing std::promise(std::move(other)).swap(*this).

2) promise is not copy-assignable.

Parameters

other

-

another promise to acquire the state from

Return value

*this
