Uptrace for Rust

Introduction

uptrace-rust is an OpenTelemery Rust distribution configured to export traces and metrics to Uptrace.

Quickstart

Install uptrace-rust:

bash cargo add uptrace

Run the basic example below using the DSN from the Uptrace project settings page.

shell UPTRACE_DSN=http://project2_secret_token@localhost:14317/2 cargo run --example basic

```rust use std::{thread, time::Duration};

use opentelemetry::{ global, trace::{TraceContextExt, Tracer}, Key, KeyValue, }; use uptrace::UptraceBuilder;

[tokio::main]

async fn main() { UptraceBuilder::new() .withservicename("myservice") .withserviceversion("1.0.0") .withdeploymentenvironment("testing") .configure_opentelemetry() .unwrap();

let tracer = global::tracer("app_or_crate_name");

tracer.in_span("root-span", |cx| {
    thread::sleep(Duration::from_millis(5));

    tracer.in_span("GET /posts/:id", |cx| {
        thread::sleep(Duration::from_millis(10));

        let span = cx.span();
        span.set_attribute(Key::new("http.method").string("GET"));
        span.set_attribute(Key::new("http.route").string("/posts/:id"));
        span.set_attribute(Key::new("http.url").string("http://localhost:8080/posts/123"));
        span.set_attribute(Key::new("http.status_code").i64(200));
    });

    tracer.in_span("SELECT", |cx| {
        thread::sleep(Duration::from_millis(20));

        let span = cx.span();
        span.set_attribute(KeyValue::new("db.system", "mysql"));
        span.set_attribute(KeyValue::new("db.statement", "SELECT * FROM table"));
    });

    let span = cx.span();
    println!("{:?}", span.span_context().trace_id().to_string());
});

global::shutdown_tracer_provider();

} ```
