How to access shared state from external process

[ptondereau]

I have a project with a Tauri app that starts an Axum server like this:

fn main() {
    tauri::Builder::default()
        .setup(|app| {
            let server = http_proxy::lauch(); // == bind().serve()
            tauri::async_runtime::spawn(async move {
                server.await.expect("failed to launch http proxy");
            });
            Ok(())
        })
        .invoke_handler(tauri::generate_handler![greet])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

http-proxy is a tiny HTTP proxy (catch-all) that just modify and adds some headers to intercepted requests.
In shared state, I would like to provide a solution that bypass this interception when a flag is false or true like this:

struct AppState {
  bypass: bool // default to false
}

and use it in my handler to early return untouched request. This way, it avoids IMHO start stop management of my proxy.

Do you know how to achieve this?
BTW, my first idea was to use channel, but I struggle a lot who is responsible for spawning tasks

Can you pass the state to http_proxy::lauch?

Yes I can but what about mutating it in tauri process? Is it safe toggle the bypassstate parameter by just passing it?

I don't know. You might need an Arc<Mutex<_>>
