The class template std::future provides a mechanism to access the result of asynchronous operations Perhaps pandas wants me to do this explicitly, but i don't see how i could downcast a string to a numerical type before the replacement happens. 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. Int64 if i understand the warning correctly, the object dtype is downcast to int64 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
If valid () is false before the call to this function, the behavior is undefined. Checks if the future refers to a shared state Returned by std::promise::get_future (), std::packaged_task::get_future () or std::async ()) until the first time get () or share () is called If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting
This function may block for longer than timeout_duration due to scheduling or resource contention delays The standard recommends that a steady clock is used to measure the duration. Specifies state of a future as returned by wait_for and wait_until functions of std::future and std::shared_future 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 may refer to the same shared state
Access to the same shared state from multiple threads is safe if each thread does it through its own copy of a shared_future object.
Ensure_future vs create_task ensure_future is a method to create task from coroutine Create_task is an abstract method of abstracteventloop Different event loops can implement this function different ways. 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. Wait_until waits for a result to become available It blocks until specified timeout_time has been reached or the result becomes available, whichever comes first
The return value indicates why wait_until returned
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.
