Module spans 

Render the tracing span trace as a compact breadcrumb.

The span trace carries the instrumented spans active when the error was created plus their field values (request_id, course_id, …). Rendered root-first as http_request{request_id=…} › send_message{course_id=…} for request context at a glance.

Structs

SpanEntry

One captured span reduced to its name and formatted fields.

Constants

MAX_FIELDS_LEN 🔒

Maximum length of a single span’s rendered field string before truncation.

OUR_TARGET_PREFIX 🔒

Only include spans from our own instrumentation; runtime/library spans add noise.
