Now that we have covered the fundamentals of signals, let's delve into the world of handling signals in Rust! Unlike C, where signal handling is built into the language modules, Rust provides several libraries that enable developers to handle signals with ease. Libraries such as signal_hook, nix, libc, and tokio handle signals that primarily use C bindings to make it possible to work with signals.
In the above code, we initialize the type of signal by calling its signalKind method. SIGINT is referred to as interrupt(), and SIGTERM is referred to as terminate(). You can find the methods for others in the documentation. In our case, we are calling the interrupt() kind:
