### Cachear el esquema de OpenAPI { #cache-the-openapi-schema }

Puedes usar la propiedad `.openapi_schema` como un "cache", para almacenar tu esquema generado.

De esa forma, tu aplicación no tendrá que generar el esquema cada vez que un usuario abra la documentación de tu API.

### Zwischenspeichern des OpenAPI-Schemas { #cache-the-openapi-schema }

Sie können die Eigenschaft `.openapi_schema` als „Cache“ verwenden, um Ihr generiertes Schema zu speichern.

Auf diese Weise muss Ihre Anwendung das Schema nicht jedes Mal generieren, wenn ein Benutzer Ihre API-Dokumentation öffnet.

Em um cenário avançado onde você precise que a dependência seja calculada em cada passo (possivelmente várias vezes) de uma requisição em vez de utilizar o valor em "cache", você pode definir o parâmetro `use_cache=False` em `Depends`:

    
    // READ_CACHING for directories means:
    // - Can cache directory enumeration results
    // - Can cache file existence queries
    // - Can cache basic file attributes
    
    // HANDLE_CACHING for directories means:
    // - Can keep directory handle open
    // - Can cache subdirectory handles
    
    // WRITE_CACHING for directories means:
    // - Can cache file creation/deletion notifications

	// Check for overflows.
	// https://github.com/minio/minio/issues/8035
	// XFS can show wrong values at times error out
	// in such scenarios.
	if info.Free > info.Total {
		return info, fmt.Errorf("detected free space (%d) > total drive space (%d), fs corruption at (%s). please run 'fsck'", info.Free, info.Total, path)
	}
	info.Used = info.Total - info.Free

	if firstTime {
		bfs, err := blockdevice.NewDefaultFS()
		if err == nil {

		t.Fatalf("expected time to be un-equal: %s == %s", t1, t3)
	}
}

func TestCache(t *testing.T) {
	cache := New[time.Time]()
	t.Parallel()
	cache.InitOnce(2*time.Second, Opts{},
		func(ctx context.Context) (time.Time, error) {
			return time.Now(), nil
		},
	)

	t1, _ := cache.Get()

	t2, _ := cache.Get()

	if !t1.Equal(t2) {
		t.Fatalf("expected time to be equal: %s != %s", t1, t2)
	}
