//! [Jaeger][jaeger] client library created on top of [rustracing].
//!
//! [jaeger]: https://github.com/jaegertracing/jaeger
//! [rustracing]: https://crates.io/crates/rustracing
//!
//! # Examples
//!
//! ```
//! use rustracing::sampler::AllSampler;
//! use rustracing_jaeger::Tracer;
//! use rustracing_jaeger::reporter::JaegerCompactReporter;
//!
//! // Creates a tracer
//! let (tracer, 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.try_recv().unwrap();
//! assert_eq!(span.operation_name(), "sample_op");
//!
//! // Reports this span to the local jaeger agent
//! let reporter = JaegerCompactReporter::new("sample_service").unwrap();
//! reporter.report(&[span]).unwrap();
//! ```
