This chapter focuses on epoll, which is specific to Linux. Unfortunately, epoll is not part of the Portable Operating System Interface (POSIX) standard, so this example will require you to run Linux and won’t work with macOS, BSD, or Windows operating systems.

If you’re on a machine running Linux, you’re already set and can run the examples without any further steps.

If you’re on Windows, my recommendation is to set up WSL (https://learn.microsoft.com/en-us/windows/wsl/install), if you haven’t already, and install Rust on the Linux operating system running on WSL.
