std::shared_future<T>::shared_future: std::shared_future<T>::shared_future
NAME
std::shared_future<T>::shared_future - std::shared_future<T>::shared_future
Synopsis
shared_future() noexcept; (1) (since C++11)
shared_future( const shared_future& other ); (since C++11)
shared_future( const shared_future& other ) noexcept; (2) (since C++17)
shared_future( std::future<T>&& other ) noexcept; (3) (since C++11)
shared_future( shared_future&& other ) noexcept; (4) (since C++11)
Constructs a new shared_future.
1) Default constructor. Constructs an empty shared future, that doesn't refer to a shared state, that is valid() == false.
2) Constructs a shared future that refers to the same shared state, if any, as other.
3-4) Transfers the shared state held by other to *this. After the construction, other.valid() == false, and this->valid() returns the same value as other.valid() would have returned before the construction.
Parameters
other - another future object to initialize with
