Hug fue uno de los primeros frameworks en implementar la declaración de tipos de parámetros API usando las anotaciones de tipos de Python. Esta fue una gran idea que inspiró a otras herramientas a hacer lo mismo.

Usaba tipos personalizados en sus declaraciones en lugar de tipos estándar de Python, pero aún así fue un gran avance.

  @CanIgnoreReturnValue
  Type[] resolveTypesInPlace(Type[] types) {
    for (int i = 0; i < types.length; i++) {
      types[i] = resolveType(types[i]);
    }
    return types;
  }

  private Type[] resolveTypes(Type[] types) {
    Type[] result = new Type[types.length];
    for (int i = 0; i < types.length; i++) {
      result[i] = resolveType(types[i]);
    }
    return result;
  }

  @CanIgnoreReturnValue
  Type[] resolveTypesInPlace(Type[] types) {
    for (int i = 0; i < types.length; i++) {
      types[i] = resolveType(types[i]);
    }
    return types;
  }

  private Type[] resolveTypes(Type[] types) {
    Type[] result = new Type[types.length];
    for (int i = 0; i < types.length; i++) {
      result[i] = resolveType(types[i]);
    }
    return result;
  }

Lo mismo sucedería si tuvieras algo como un <abbr title='Una unión entre múltiples tipos significa "cualquiera de estos tipos".'>union</abbr> entre diferentes tipos donde uno o más de ellos no son tipos válidos de Pydantic, por ejemplo esto fallaría 💥:
