[bug] Exclude app_icon (Vec<u8>) from tracing instrumentation (wry::ipc::handle)

[mihirsamdarshi]

Describe the bug

I am trying to debug an application that I have written with Tauri. I enabled the tracing feature. When the app tries to handle a tauri::command my application freezes because it is trying to log the entire app icon as a Vec<u8>.

The log looks like the following:

2024-08-25T20:22:57.189423Z DEBUG wry::ipc::handle:window::on_message{self=Window { window: DetachedWindow { label: "main", dispatcher: WryDispatcher { window_id: 7354931179636518423, context: Context { main_thread_id: ThreadId(1), proxy: EventLoopProxy { <other stuff here> }, TauriConfig{ <other stuff here...>, app_icon: Some([105, 99, 110, 115, 0, 7, 53, 156, 105, 99, 49, 50, 0, 0, 18, 110, 137, 80, 78, 71, 13, 10, 26, 10, 0, 0, 0, 13, 73, 72, 68, 82, 0, 0, 0, 64, 0, 0, 0, 64, 8, 6, 0, 0, 0, 170, 105, 113, 222, 0, 0, 18, 45, 73, 68, 65, 84, 120, 156, 229, 91, 105, 116, 28, 213, 149, 190, 146, 122, 239, 214, 210, 146, 90, 82, 183, 118, 75, 224, 93, 216... 

Reproduction

Create a tauri application, add an app icon, then, enable tracing in your Cargo.toml,

In Cargo.toml:

[features]
tauri-tracing = ["tauri/tracing"]

Set up tracing in your application

fn setup_tracing() {
    let filter: Directive = LevelFilter::DEBUG.into();

    let env_filter = EnvFilter::builder()
        .with_default_directive(filter)
        .from_env_lossy()
        .add_directive("h2=warn".parse().unwrap())
        .add_directive("rustls=warn".parse().unwrap())
        .add_directive("yup_oauth2::authenticator=warn".parse().unwrap())
        .add_directive("hyper=warn".parse().unwrap());

    let subscriber = tracing_subscriber::registry()
        .with(tracing_subscriber::fmt::layer().with_filter(env_filter));

    #[cfg(all(debug_assertions, not(windows)))]
    // set up tokio-console if we're running in debug mode
    let subscriber = subscriber.with(console_subscriber::spawn());

    subscriber.init();
}

fn main() {
    let _sentry_guard = setup_tracing();

    let state = InfraState::new();

    tauri::Builder::default()
        .manage(state)
        .on_page_load(page_load_handler)
        .invoke_handler(tauri::generate_handler![
             a_command
        ])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Then run the application:

RUST_DEBUG=1 NODE_TLS_REJECT_UNAUTHORIZED=0 RUST_BACKTRACE=full NO_COLOR=true yarn tauri dev -v --features tauri-tracing > app.log 2>&1

Expected behavior

The app_icon isn't necessary (in my opinion), and just clogs the logs. I'm hoping you can exclude it?
