O **FastAPI** gera um "*schema*" com toda a sua API usando o padrão **OpenAPI** para definir APIs.

#### "*Schema*" { #schema }

Um "*schema*" é uma definição ou descrição de algo. Não o código que o implementa, mas apenas uma descrição abstrata.

#### API "*schema*" { #api-schema }

	r := z.rebalMeta
	poolStats := r.PoolStats[poolIdx]
	if poolStats.Info.Status == rebalCompleted {
		return true
	}

	pfi := float64(poolStats.InitFreeSpace+poolStats.Bytes) / float64(poolStats.InitCapacity)
	// Mark pool rebalance as done if within 5% from PercentFreeGoal.
	if diff := math.Abs(pfi - r.PercentFreeGoal); diff <= 0.05 {
		r.PoolStats[poolIdx].Info.Status = rebalCompleted
		r.PoolStats[poolIdx].Info.EndTime = time.Now()

* Es können **mehrere Prozesse** desselben **Programms** gleichzeitig ausgeführt werden.

Wenn Sie sich den „Task-Manager“ oder „Systemmonitor“ (oder ähnliche Tools) in Ihrem Betriebssystem ansehen, können Sie viele dieser laufenden Prozesse sehen.

    opt Tasks
        operation -->> tasks: Send background tasks
    end
    opt Raise other exception
        tasks -->> tasks: Handle exceptions in the background task code
    end

Ancak FastAPI olmadan `async` / `await` kullanmak istiyorsanız, <a href="https://docs.python.org/3/library/asyncio-task.html#coroutine" class="external-link" target="_blank">resmi Python belgelerini kontrol edin</a>.

### Asenkron kodun diğer biçimleri

Bu `async` ve `await` kullanimi oldukça yenidir.
