Document differences to tower_http trace

[lcmgh]

There is also https://docs.rs/tower-http/0.5.2/tower_http/trace/index.html

I wonder how this crate is different?

Edit: What I understand is that tower_http::trace exists to get request/response traces and this crate exists to get the span connection to parent otel trace ids from incoming requests and not to log request/Response data?

See tower-rs/tower-http#508

If this layer is also supposed to generate tracing messages I wonder how one could get same tracing msg behavior as with this code based on tower_http::trace:

let trace_layer = TraceLayer::new(SharedClassifier::new(GrpcErrorsAsFailures::new()))
  .make_span_with(|request: &http::Request<_>| {
      tracing::info_span!(
          "request",
          otel.name = format!("{} {}", request.method(), request.uri().path()),
          method = %request.method(),
          uri = %request.uri(),
          version = ?request.version(),
      )
  })
  .on_request(DefaultOnRequest::default().level(Level::INFO))
  .on_response(DefaultOnResponse::default().level(Level::INFO))
  .on_eos(DefaultOnEos::default().level(Level::INFO))
  .on_failure(DefaultOnFailure::default().level(Level::ERROR));
