Давайте немного углубимся в детали.

FastAPI использует стандарт для построения Python‑веб‑фреймворков и серверов под названием <abbr title="Asynchronous Server Gateway Interface – Асинхронный шлюзовый интерфейс сервера">ASGI</abbr>. FastAPI — ASGI-веб‑фреймворк.

In this section we'll see how to use other middlewares.

## Adding ASGI middlewares { #adding-asgi-middlewares }

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

 * <p>This class is GWT-compatible.
 *
 * <h3>Purpose</h3>
 *
 * <p>The main purpose of {@code ListenableFuture} is to help you chain together a graph of
 * asynchronous operations. You can chain them together manually with calls to methods like {@link
 * Futures#transform(ListenableFuture, com.google.common.base.Function, Executor) Futures.transform}

## Servidores ASGI { #asgi-servers }

Vamos nos aprofundar um pouco mais em detalhes.

FastAPI utiliza um padrão para construir frameworks e servidores web em Python chamado <abbr title="Asynchronous Server Gateway Interface – Interface de Gateway de Servidor Assíncrono">ASGI</abbr>. FastAPI é um framework web ASGI.

	targetIDSet := evnot.bucketRulesMap[args.BucketName].Match(args.EventName, args.Object.Name)
	evnot.RUnlock()

	if len(targetIDSet) == 0 {
		return
	}

	// If MINIO_API_SYNC_EVENTS is set, send events synchronously.
	evnot.targetList.Send(args.ToEvent(true), targetIDSet, globalAPIConfig.isSyncEventsEnabled())
}

type eventArgs struct {
	EventName    event.Name
	BucketName   string
	Object       ObjectInfo
