std::promise

Member functions

promise::promise

promise::~promise

promise::operator=

promise::swap

Getting the result

promise::get_future

Setting the result

Defined in header <future>
template< class R > void swap( promise<R> &lhs, promise<R> &rhs ) noexcept;		(since C++11)

Specializes the std::swap algorithm for std::promise. Exchanges the shared state of lhs with that of rhs. Effectively calls lhs.swap(rhs).

Parameters

lhs, rhs

-

promises whose states to swap

Return value

(none)
