Eğer **FastAPI**'de bir dependency olarak bir "callable" verirseniz, FastAPI o "callable" için parametreleri analiz eder ve bunları *path operation function* parametreleriyle aynı şekilde işler. Sub-dependency'ler dahil.

Bu, hiç parametresi olmayan callable'lar için de geçerlidir. Tıpkı hiç parametresi olmayan *path operation function*'larda olduğu gibi.

또한 코드의 다른 영역에서 사용할 수 있는 lifespan 상태를 처리하는 방법도 포함되어 있습니다.

## Monter une sous-application { #mounting-a-sub-application }

Si vous avez besoin de monter une sous‑application (comme décrit dans [Sous‑applications - montages](sub-applications.md)) tout en utilisant un proxy avec `root_path`, vous pouvez le faire normalement, comme vous vous y attendez.

Usar `BackgroundTasks` también funciona con el sistema de inyección de dependencias, puedes declarar un parámetro de tipo `BackgroundTasks` en varios niveles: en una *path operation function*, en una dependencia (dependable), en una sub-dependencia, etc.

**FastAPI** sabe qué hacer en cada caso y cómo reutilizar el mismo objeto, de modo que todas las tareas en segundo plano se combinan y ejecutan en segundo plano después:

			ioStats:       map[string]driveIOStatMetrics{},
		}

		currentStats := getCurrentDriveIOStats()
		now := time.Now().UTC()

		prevDriveIOStatsMu.Lock()
		if prevDriveIOStats != nil {
			duration := now.Sub(prevDriveIOStatsRefreshedAt)
			if duration.Seconds() > 1 {
				for d, cs := range currentStats {
					if ps, found := prevDriveIOStats[d]; found {
						v.ioStats[d] = getDriveIOStatMetrics(getDiffStats(ps, cs), duration)

	var avg float64
	if l.successRequestCount > 0 {
		avg = l.rttMsSum / float64(l.successRequestCount)
	}
	now := time.Now().UTC()
	return Metrics{
		LastReachableSecs:   now.Sub(o.serviceMetrics.LastCheckSuccess).Seconds(),
		LastUnreachableSecs: now.Sub(o.serviceMetrics.LastCheckFailure).Seconds(),
		TotalRequests:       l.failedRequestCount + l.successRequestCount,
		FailedRequests:      l.failedRequestCount,
		AvgSuccRTTMs:        avg,

Da mesma forma, você pode utilizar `finally` para garantir que os passos de saída são executados, com ou sem exceções.

## Subdependências com `yield` { #sub-dependencies-with-yield }

Você pode ter subdependências e "árvores" de subdependências de qualquer tamanho e forma, e qualquer uma ou todas elas podem utilizar `yield`.
