cf-rustracing
OpenTracing API for Rust.
Examples
use cf_rustracing::sampler::AllSampler;
use cf_rustracing::tag::Tag;
use cf_rustracing::Tracer;
use std::thread;
use std::time::Duration;
#[tokio::main]
async fn main() {
// Creates a tracer
let (tracer, mut span_rx) = Tracer::new(AllSampler);
{
// Starts "parent" span
let parent_span = tracer.span("parent").start_with_state(());
thread::sleep(Duration::from_millis(10));
{
// Starts "child" span
let mut child_span = tracer
.span("child_span")
.child_of(&parent_span)
.tag(Tag::new("key", "value"))
.start_with_state(());
child_span.log(|log| {
log.error().message("a log message");
});
} // The "child" span dropped and will be sent to `span_rx`
} // The "parent" span dropped and will be sent to `span_rx`
println!("# SPAN: {:?}", span_rx.recv().await);
println!("# SPAN: {:?}", span_rx.recv().await);
}
As an actual usage example of the crate and an implementation of the OpenTracing API, it may be helpful to looking at rustracing_jaeger crate.
