I have this function that is working perfectly fine with opentelemetry = { version = "0.17", features = ["tokio"] } and opentelemetry-jaeger = { version = "0.16", features = ["rt-tokio"] }

pub fn get_subscriber(name: String, env_filter: String) -> impl Subscriber + Sync + Send {
    // Building the jaeger layer, if needed
    let telemetry = if std::env::var("JAEGER_ENABLED").is_ok() {
        let tracer = opentelemetry_jaeger::new_pipeline()
            .with_service_name(&name)
            .install_batch(opentelemetry::runtime::Tokio)
            .unwrap();
        Some(tracing_opentelemetry::layer().with_tracer(tracer))
    } else {
        None
    };

    let env_filter =
        EnvFilter::try_from_default_env().unwrap_or_else(|_| EnvFilter::new(env_filter));
    let formatting_layer = BunyanFormattingLayer::new(name, std::io::stdout);

    Registry::default()
        .with(env_filter)
        .with(JsonStorageLayer)
        .with(formatting_layer)
        .with(sentry_tracing::layer())
        .with(telemetry)
}

Everything works fine like this, and I can find my trace in Jaeger when it is enabled.

Since I update to opentelemetry = { version = "0.18", features = ["rt-tokio"] } and opentelemetry-jaeger = { version = "0.17", features = ["rt-tokio"] } It won't compile anymore

error: could not compile `rss-common` due to 6 previous errors

I looked at the change log of the said crates, and find nothing obvious about what I should change to make it compile again

What should I change?

Simple. You're using tracing-opentelemetry to connect the tracing and opentelemetry ecosystems, but the crate has not been updated to support v0.18 of opentelementry as of yet. Without this layer of functionality, you cannot update to the latest opentelemetry version, unless you want to forgo tracing integration.

I see the developers have merged in support for the latest version, but it appears to have not been published yet. Be patient. :)
