sortByPriority static method

List<SintMiddleware> sortByPriority(List<SintMiddleware> middlewares)

Stable sort by SintMiddleware.priority: among equal priorities the original declaration order is preserved (Dart's List.sort is NOT stable). Shared by MiddlewareRunner and SintDelegate.runMiddleware so both middleware pipelines agree on ordering (1.5.0).

Implementation

static List<SintMiddleware> sortByPriority(
    List<SintMiddleware> middlewares) {
  final indexed = <MapEntry<int, SintMiddleware>>[
    for (var i = 0; i < middlewares.length; i++)
      MapEntry(i, middlewares[i]),
  ];
  indexed.sort((a, b) {
    final cmp = a.value.priority.compareTo(b.value.priority);
    return cmp != 0 ? cmp : a.key.compareTo(b.key);
  });
  return [for (final entry in indexed) entry.value];
}
