Struct StructuredMakeSpan 

pub struct StructuredMakeSpan { /* private fields */ }

Span maker that records service, request, route, and trace context fields.

The span includes service.name, service.version, deployment.environment, request.id, trace.id, http.method, http.route, and http.target. Request ID and trace ID are read from x-request-id and traceparent headers respectively; use the request ID middleware before tracing when you need every request span to have an ID.

impl StructuredMakeSpan

pub fn new(config: LoggingConfig) -> Self

pub fn route(self, route: impl Into<Cow<'static, str>>) -> Self

When unset, the span maker falls back to Axum’s axum::extract::MatchedPath extension and then "<unknown>".
