Anyway, in any of the cases above, FastAPI will still work asynchronously and be extremely fast.

But by following the steps above, it will be able to do some performance optimizations.

## Technical Details

Modern versions of Python have support for **"asynchronous code"** using something called **"coroutines"**, with **`async` and `await`** syntax.

Let's see that phrase by parts in the sections below:

	OutputLocation   OutputLocation     `xml:"OutputLocation,omitempty"`
}

// Maximum 2MiB size per restore object request.
const maxRestoreObjectRequestSize = 2 << 20

// parseRestoreRequest parses RestoreObjectRequest from xml
func parseRestoreRequest(reader io.Reader) (*RestoreObjectRequest, error) {
	req := RestoreObjectRequest{}

				}
				hdr.Xattrs[k[len(paxSchilyXattr):]] = v
			}
		}
		if err != nil {
			return ErrHeader
		}
	}
	hdr.PAXRecords = paxHdrs
	return nil
}

// parsePAX parses PAX headers.
// If an extended header (type 'x') is invalid, ErrHeader is returned.
func parsePAX(r io.Reader) (map[string]string, error) {
	buf, err := readSpecialFile(r)
	if err != nil {
		return nil, err
	}

	xnet "github.com/minio/pkg/v3/net"
)

const (
	copyDirective    = "COPY"
	replaceDirective = "REPLACE"
	accessDirective  = "ACCESS"
)

// Parses location constraint from the incoming reader.
func parseLocationConstraint(r *http.Request) (location string, s3Error APIErrorCode) {
	// If the request has no body with content-length set to 0,

	if t, ok := config.Tiers[tierName]; ok {
		return t.Type, true
	}
	return madmin.Unsupported, false
}

// Add adds tier to config if it passes all validations.
func (config *TierConfigMgr) Add(ctx context.Context, tier madmin.TierConfig, ignoreInUse bool) error {
	config.Lock()
	defer config.Unlock()

	// check if tier name is in all caps

      }
      asciiDigits = result;

    static int digit(char c) {
      return (c < 128) ? asciiDigits[c] : -1;
    }
  }
