Minimal logging setup

axum uses the tracing and tracing-subscriber for logging so we need to include both.

{{#include ../../examples/minimal-tracing/Cargo.toml}

#![allow(unused)]
fn main() {
{{#include ../../examples/minimal-tracing/src/main.rs}
}

When we start the application with cargo run we'll see line like this on the terminal:

2025-03-17T08:39:04.089621Z DEBUG example_minimal_tracing: listening on 127.0.0.1:3000

When we access the main page with a browser we'll see two more lines:

2025-03-17T08:39:27.044996Z TRACE axum::serve: connection 127.0.0.1:58560 accepted
2025-03-17T08:39:27.045345Z DEBUG example_minimal_tracing: in handler
