daemonize-me VS signal-hook

Hey everyone,I'm new to rust. I'm trying to create a background service using daemonize-me that will send post request every hour, when I restart my computer or run kill $(pidof xxx) I want to do some cleanup for example delete the pid file.

I want to use signal-hook-tokio from here: https://github.com/vorner/signal-hook/blob/master/signal-hook-tokio/src/lib.rs. It says that I need to enable a feature to make the next() method works. I did that, but I still get an error:

If you're interested in the techniques people use here, you might take a look at signalfd - which gives you a way to read signals as-if through a file pipe (so you can use it with things like select/epoll loops) - or signal-hook's implementation of the signal-pipe pattern (which makes use of the fact that write is on the list of async-signal-safe system calls).

This may change, but as of now, the crate documentation has 2 examples on the front page - one that is very simple, which we will take a closer look at below, and one that is overly complex, which uses features that are unlikely to be commonly needed, and won't compile without enabling extra features. We'll slowly work our way from the simple example, to a more complex one that resembles the one in the documentation.
