Unlike std::future, which is only moveable (so only one instance can refer to any particular asynchronous result), std::shared_future is copyable and multiple shared future objects
std::future<T>::valid
Checks if the future refers to a shared state. This is the case only for futures that were not default-constructed or moved from (i.e. returned by std::promise::get_future (),
std::future
The class template std::future provides a mechanism to access the result of asynchronous operations: An asynchronous operation (created via std::async, std::packaged_task,
std::future<T>::get
The get member function waits (by calling wait ()) until the shared state is ready, then retrieves the value stored in the shared state (if any). Right after calling this function, valid () is false.
std::future<T>::~future
These actions will not block for the shared state to become ready, except that they may block if all following conditions are satisfied: The shared state was created by a call to std::async.
