Wrapping up our quick introduction to the C++ futures library , we come to the last two parts: std:: future and std:: shared_future .

The std:: future is the starting point. It is a move-only class that this takes the source and forwards its wait and wait_for methods to the source , and forwards its get method to consume .

Forwarding the get to consume means that you can call get only once.
