  /**
   * Decorator that binds guards to the scope of the controller or method,
   * depending on its context.
   *
   * When `@UseGuards` is used at the controller level, the guard will be
   * applied to every handler (method) in the controller.
   *
   * When `@UseGuards` is used at the individual handler level, the guard
   * will apply only to that specific method.
   *
   * @param guards a single guard instance or class, or a list of guard instances
   * or classes.
   *
   * @see [Guards](https://docs.nestjs.com/guards)
   *
   * @usageNotes
   * Guards can also be set up globally for all controllers and routes
   * using `app.useGlobalGuards()`.  [See here for details](https://docs.nestjs.com/guards#binding-guards)
