How to shutdown server with code in linux

[hanaTsuk1]

In windows, I can use windows_service and cancel_recv to shutdown server
I have read the relevant code, but in linux, I don't know how to do it
Could you please provide some assistance

Unfortunately, there is no exposed API to shout down the server gracefully on demand.
You have to send to the process a termination signal like SIGTERM.

Thanks for your reply
Will this feature be added in the future?

[joseluisq]

I do not know but you can always suggest something or open a feature request explaining your use case.

I am creating a small tool based on static web server
Here is my use case
https://github.com/yuri-app/yuri/blob/master/src-tauri/src/main.rs#L40

I am a beginner in Rust, so I am not sure if the following ideas are correct or not
Why not add a cancel_recv to wait_for_signals so that all platforms can directly control the server

Because that function was initially thought to just wait for Linux/Unix termination signals only. Later on, Windows support came along which does not have a termination signal concept and uses a channel to wait for an incoming ctrl+c. That's why both defer in implementation.
Anyway, I agree that adding support for a cancel_recv should be convenient for library users to shout down the server gracefully on demand.

I could propose something in the coming weeks, so stay tuned.
