- std::future - cppreference. com
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, or std::promise) can provide a std::future object to the creator of that asynchronous operation The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std
- std::future lt;T gt;::share - cppreference. com
Transfers the shared state of *this, if any, to a std::shared_future object Multiple std::shared_future objects may reference the same shared state, which is not possible with std::future After calling share on a std::future, valid() == false
- Pandas replace and downcasting deprecation since version 2. 2. 0

- What is a Future and how do I use it? - Stack Overflow
A future represents the result of an asynchronous operation, and can have two states: uncompleted or completed Most likely, as you aren't doing this just for fun, you actually need the results of that Future<T> to progress in your application You need to display the number from the database or the list of movies found
