runWithActiveGlobalSpan static method

Future<void> runWithActiveGlobalSpan(String spanId, Future<void> block())

Runs block in a zone where getActiveGlobalSpanId returns spanId.

Implements CoralogixGlobalSpan.withContext via runZonedGuarded(..., zoneValues: {#cxActiveSpanId: spanId}) so the active id survives await (Q5).

A Completer is used instead of late final so that async errors captured by runZonedGuarded's error handler after block has already returned a future do not trigger a LateInitializationError on reassignment.

Implementation

static Future<void> runWithActiveGlobalSpan(
  String spanId,
  Future<void> Function() block,
) {
  final completer = Completer<void>();
  runZonedGuarded(
    () {
      block().then(
        (_) {
          if (!completer.isCompleted) completer.complete();
        },
        onError: (Object error, StackTrace stack) {
          if (!completer.isCompleted) completer.completeError(error, stack);
        },
      );
    },
    (Object error, StackTrace stack) {
      if (!completer.isCompleted) completer.completeError(error, stack);
    },
    zoneValues: <Symbol, Object?>{cxActiveSpanIdKey: spanId},
  );
  return completer.future;
}
