std::promise
Member functions
promise::operator=
Getting the result
Setting the result
Non-member Functions
Helper Classes
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.[edit] Parameters
other
-
another
promise to acquire the state from
[edit] Return value
*this
