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