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.

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::future.
The code above might look ugly, but all you have to understand is that the FutureBuilder widget takes two arguments: future and builder, future is just the future you want to use, while builder is a function that takes two parameters and returns a widget. FutureBuilder will run this function before and after the future completes.
In summary: std::future is an object used in multithreaded programming to receive data or an exception from a different thread; it is one end of a single-use, one-way communication channel between two threads, std::promise object being the other end.
Now, this causes the following warning: FutureWarning: Downcasting object dtype arrays on .fillna, .ffill, .bfill is deprecated and will change in a future version. Call result.infer_objects (copy=False) instead. I don't know what I should do instead now. I certainly don't see how infer_objects(copy=False) would help as the whole point here is indeed to force converting everything to a string ...
A future statement is a directive to the compiler that a particular module should be compiled using syntax or semantics that will be available in a specified future release of Python. The future statement is intended to ease migration to future versions of Python that introduce incompatible changes to the language. It allows use of the new features on a per-module basis before the release in ...

Considerations When future grants are defined on the same object type for a database and a schema in the same database, the schema-level grants take precedence over the database level grants, and the database level grants are ignored. This behavior applies to privileges on future objects granted to one role or different roles. Reproducible example:
- Move constructor. Constructs a std::future with the shared state of other using move semantics. After construction, other.valid() == false.
Return value A std::experimental::future object associated with the shared state created by this object. valid()==true for the returned object.
The error: SyntaxError: future feature annotations is not defined usually related to an old version of python, but my remote server has Python3.9 and to verify it - I also added it in my inventory and I printed the ansible_facts to make sure.
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::packaged_task::get_future () or std::async ()) until the first time get () or share () is called. The behavior is undefined if any member function other than the destructor, the move-assignment operator, or valid is ...
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. The shared state is not yet ready. The current object was the last reference to the shared state. (since C++14)
