pub struct Tracer<S, T> { /* fields omitted */ }

Tracer.

Examples

use rustracing::Tracer;
use rustracing::sampler::AllSampler;

let (tracer, span_rx) = Tracer::new(AllSampler);
{
   let _span = tracer.span("foo").start_with_state(());
}
let span = span_rx.try_recv().unwrap();
assert_eq!(span.operation_name(), "foo");
