* Add http.route. * Align all fields with OpenTelemetry's semantic conventions. * Add span kind. * Emit event for errors. Add OTEL status code. * Create otel.status_code field as empty. * Fix errors. * Add (feature-gated) support for OpenTelemetry span propagation. * Capture the trace id as an attribute on the span. * Change message. * Log the newly-generated trace id if there is no parent context. * Define a root_span macro as a stepping stone to allow crate users to add their own fields to the root span. * Add comments. * mut is no longer necessary. * Allow users to customise generation of the root span. Split recording fields on span end from emission of log record. Make log record on error optional via feature flag. * Provide constructor + default implementation. * Explode into multiple modules. Fix various paths/private imports in root_span. * Rename module to root_span_macro. * Add a new extractor to retrieve the root span. * Document crate. * Docs! * Add section on OTEL. * Mention actix-web-opentelemetry. * Add OpenTelemetry example. * Improve readme. * Add custom root span example.

Custom root span
Running
You can launch this example with
cargo run
An actix-web application will be listening on port 8080.
You can fire requests to it with:
curl -v http://localhost:8080/hello
Hello world!
or
curl -v http://localhost:8080/hello/my-name
Hello my-name!
Visualising traces
Spans will be also printed to the console in JSON format, as structured log records.
You can look at the exported spans in your browser by visiting http://localhost:16686 if you launch a Jaeger instance:
docker run -d -p6831:6831/udp -p6832:6832/udp -p16686:16686 jaegertracing/all-in-one:latest
