tower_http::trace: How to entirely skip certain requests?

[lcmgh]

I'd like to skip tracing of certain methods. I cannot see how this can be done as make_span_with requires return type Span

• https://docs.rs/tower-http/latest/tower_http/trace/trait.MakeSpan.html
• https://docs.rs/tracing/0.1.40/tracing/span/struct.Span.html

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));

You can return Span::none.
