Can't get tracing to work

[Dominux]

Hi, I'm trying to set up logging/tracing. But it seems to be not working at all. I feel like I'm doing something completely wrong cause in all other frameworks I've used in my experience it wasn't a problem at all, I was even configuring logging. But here it seems like it just traces nothing no matter what features I toggle or what example from the docs I implement

So, here's my deps:

axum = { version = "0.6.20", features = ["tracing"]}
tokio = { version = "1.33.0", features = ["full"] }
tower-http = { version = "0.4.4", features = ["trace"] }
tracing = "0.1.40"
tracing-subscriber = { version = "0.3.17", features = ["env-filter"]} 

And my code:

use std::net::{IpAddr, Ipv4Addr, SocketAddr};

use axum::{routing::get, Router};
use tracing_subscriber::{layer::SubscriberExt, util::SubscriberInitExt};

const ADDR: SocketAddr = SocketAddr::new(IpAddr::V4(Ipv4Addr::new(0, 0, 0, 0)), 8080);

#[tokio::main]
async fn main() {
    tracing_subscriber::registry()
        .with(
            tracing_subscriber::EnvFilter::try_from_default_env().unwrap_or_else(|_| {
                "my_app=debug,tower_http=debug,axum::rejection=trace".into()
            }),
        )
        .with(tracing_subscriber::fmt::layer())
        .init();

    // build our application with a single route
    let app = Router::new().route("/", get(|| async { "Hello, World!" }));

    // run it
    tracing::debug!("listening on {ADDR}");
    axum::Server::bind(&ADDR)
        .serve(app.into_make_service())
        .await
        .unwrap();
}

So here I got a debug message that... doesn't print anything. And it doesn't print anything also no matter whether I try to change to tracing::info! or to tracing::error!. And it doesn't print anything on requests.

What am I missing?

I’m traveling now so can’t run the code. Try asking in the tracing repo since this isn’t related to axum.

Completely dumb situation of mine. It was caused by me using wrong make command:

run:
    cd ./my_app && cargo run | cd -

So when I tried to write just a simple rust println! program it was giving me an Broken pipe (os: error 32) and it was unobvious af. But once I tried to describe my problem to my wife like she's 5 I noticed that error and it made me feel like I'm 5 not her XD
