```Python

Когда блок `with` завершается, он обязательно закрывает файл, даже если были исключения.

Maven Model

 This is strictly the model for Maven POM (Project Object Model) in <<<org.apache.maven.model>>> package,
 delegating content to {{{../api/maven-api-model/index.html}Maven 4 API immutable model}}. All the effective model
 building logic from multiple POMs and building context is done in {{{../maven-model-builder/}Maven Model Builder}}.

 The following are generated from this model:

	health       *diskHealthTracker
	healthCheck  bool

	metricsCache *cachevalue.Cache[DiskMetrics]
	diskCtx      context.Context
	diskCancel   context.CancelFunc
}

func (p *xlStorageDiskIDCheck) getMetrics() DiskMetrics {
	p.metricsCache.InitOnce(5*time.Second,
		cachevalue.Opts{},
		func(ctx context.Context) (DiskMetrics, error) {
			diskMetric := DiskMetrics{
				LastMinute: make(map[string]AccElem, len(p.apiLatencies)),

	if err != nil {
		return nil, err
	}
	return c.client.Encrypt(context.Background(), keyID, plaintext, ctxBytes)
}

// DecryptKey decrypts the ciphertext with the key at the KES
// server referenced by the key ID. The context must match the
// context value used to generate the ciphertext.
func (c *kesConn) Decrypt(ctx context.Context, req *DecryptRequest) ([]byte, error) {
	aad, err := req.AssociatedData.MarshalText()
	if err != nil {

        // don't merge
    }

            boolean sourceDominant,
            Map<Object, Object> context) {
        // don't merge
    }
