In general, it probably doesn't. If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting. 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).
In Such Situation Future Grants Assigned On The Database Level Are Ignored.
Blocks until the result becomes available. Perhaps installing a previous version of. I'm wondering how this break in backwards compatibility should in general be navigated.
A Future Represents The Result Of An Asynchronous Operation, And Can Have Two States:
An asynchronous operation (created via std::async, std::packaged_task,. 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). Valid() == true after the call.
The Behavior Is Undefined If Valid() == False Before The Call To This Function.
This function may block for longer than timeout_duration due to. If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. In this case it does work.
Right After Calling This Function, Valid () Is False.
Most likely, as you aren't doing this just for fun, you actually need the. The class template std::future provides a mechanism to access the result of asynchronous operations: If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting.
The Behavior Is Undefined If Valid () Is False Before The Call To This.
Std::future is an object used in multithreaded programming to receive data or an exception from a different thread; One plausible scenario is existence of another future grants that are assigned on schema level to different role. In general, it probably doesn't.
