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.
C++ includes built-in support for threads, atomic operations, mutual exclusion, condition variables, and futures.
future (const future &) = delete; ~future (); future & operator =(const future &) = delete; future & operator =(future &&) noexcept; shared_futurewait_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 ...
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.
The class template std::packaged_task wraps any Callable target (function, lambda expression, bind expression, or another function object) so that it can be invoked asynchronously. Its return value or exception thrown is stored in a shared state which can be accessed through std::future objects.
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 ...

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.

So the question is: What are environment variables, like the executable PATH, and how can I change and use them on major operating systems? A good answer would include a simple explanation of what environment variables and especially PATH mean to the OS, as well as simple guidelines on how to set and read them accordingly.
What are PATH and other environment variables, and how can I set or use ...
What does "/" , "./", "../" represent while giving path? Let's be precise: "/"is a path which begins with a /, and thus it is an absolute path. Thus, we need to begin in the root of the file system and navigate through the folders given by name, whereas the names are separated by /s (because this is the unix path separator). Thus, / is the root of the file system with no folders entered after ...
In layman's terms, a path (or the search path) is the list of directories that will be searched for anything that you type on the command line. If you type in a built-in command like ls, it will look for a specified list of directories.
PATH is a global operating system variable that contains names of files that are to be executed without specyfing the whole path to them. For example You can just write startx to start graphic environemnt instead of /bin/some other folders/startx
What is the PATH environment variable and how do I add to it?
A path set in .bash_profile will only be set in a bash login shell (bash -l). If you put your path in .profile it will be available to your complete desktop session.
83 To permanently store your path, you have a few options. I suggest you read the Ubuntu community wiki on Environment Variables but the short answer is the best place is ~/.profile for your per-user PATH setting or /etc/profile for global settings. Change PATH: Append something to your PATH ... Override your PATH (save backup before!)

The UNIX path is an environment variable which is a list of directories in which to look for programs that you're trying to run. It allows you to avoid having to use the complete pathname for running things like /bin/ls (for example by putting /bin in the path).

Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. What does this mean ?
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 ...
