自 opentelemetry 和 opentelemetry-jaeger 更新后无法编译

Question

我有这个 function 与opentelemetry = { version = "0.17", features = ["tokio"] }和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)
}

一切都像这样正常工作，启用后我可以在 Jaeger 中找到我的踪迹。

由于我更新为opentelemetry = { version = "0.18", features = ["rt-tokio"] }和opentelemetry-jaeger = { version = "0.17", features = ["rt-tokio"] }它不会编译不再

我查看了上述板条箱的更改日志，并没有发现我应该更改什么以使其再次编译

我应该改变什么？

Answer 1

简单的。 您正在使用tracking-opentelemetry连接tracking 和 opentelemetry生态系统，但该板条箱尚未更新以支持 v0.18 的 opentelementry。 如果没有这一层功能，您将无法更新到最新的 opentelemetry 版本，除非您想放弃跟踪集成。

我看到开发人员已合并以支持最新版本，但似乎尚未发布。 要有耐心。 :)
