engineHuggingFaceResolvers static method

@visibleForTesting List<HuggingFaceResolver> engineHuggingFaceResolvers(List<InferenceEngineProvider> engines)

The Hugging Face resolvers contributed by engines that implement HuggingFaceResolverSource (e.g. LiteRtLmEngine → LitertlmManifestResolver). initialize registers these AFTER the explicit huggingFaceResolvers: list, so an app's explicit resolver wins the equal-priority tie. An engine that does not implement HuggingFaceResolverSource contributes nothing. Extracted so the derivation is unit-testable without a full initialize.

Implementation

@visibleForTesting
static List<HuggingFaceResolver> engineHuggingFaceResolvers(
  List<InferenceEngineProvider> engines,
) {
  final resolvers = <HuggingFaceResolver>[];
  for (final e in engines) {
    // Bind via pattern: HuggingFaceResolverSource is not a subtype of
    // InferenceEngineProvider, so a plain `is` check would not promote `e`.
    if (e case final HuggingFaceResolverSource source) {
      resolvers.add(source.huggingFaceResolver);
    }
  }
  return resolvers;
}
