Documentation

Examples --------

Basic Usage

use cf_rustracing::sampler::AllSampler;
use cf_rustracing_jaeger::Tracer;
use cf_rustracing_jaeger::reporter::JaegerCompactReporter;
use std::net::Ipv4Addr;

#[tokio::main]
async fn main() {
// Creates a tracer
let (tracer, mut span_rx) = Tracer::new(AllSampler);
{
let span = tracer.span("sample_op").start();
// Do something

} // The dropped span will be sent to `span_rx`

let span = span_rx.recv().await.unwrap();
assert_eq!(span.operation_name(), "sample_op");

// Reports this span to the local jaeger agent
let reporter = JaegerCompactReporter::new(
"sample_service",
(Ipv4Addr::LOCALHOST, 6831).into(),
(Ipv4Addr::LOCALHOST, 0).into(),
)
.await
.unwrap();

reporter.report(&[span]).await.unwrap();
}

Executes report.rs example
