endTrace method

@override Future<ResultDart<void, TelemetryException>> endTrace({ required String traceId, Map<String, String> attributes = const {}, })

Finishes a trace by calculating duration.

Returns ResultDart with success or TelemetryException on error.

Implementation

@override
Future<ResultDart<void, TelemetryException>> endTrace({
  required String traceId,
  Map<String, String> attributes = const {},
}) async {
  final cached = _activeTraces[traceId];
  if (cached == null) {
    return Failure(
      TelemetryException(
        message: 'Trace $traceId not found',
        code: 'TRACE_NOT_FOUND',
      ),
    );
  }

  final now = DateTime.now().toUtc();
  final updatedTrace = cached.copyWith(
    endTime: now,
    attributes: {...cached.attributes, ...attributes},
  );

  await _repository.updateTrace(
    traceId: traceId,
    endTime: now,
    attributes: updatedTrace.attributes,
  );
  _activeTraces.remove(traceId);
  return const Success(unit);
}
