Method GetInto

pkg/attributes/attributes.go:215–223

GetInto allows decoding the attribute with the given key into a given interface. The provided interface should be a pointer to a struct, to an array, or to any simple type. An error is returned if the provided interface type is not compatible with the attribute content

(key string, into interface{})

// An error is returned if the provided interface type is not compatible
// with the attribute content
func (attributes Attributes) GetInto(key string, into interface{}) error {
	var err error
	if attribute, exists := attributes[key]; exists {
		err = json.Unmarshal(attribute.Raw, into)
	} else {
		err = &KeyNotFoundError{Key: key}
	}
	return err
}

// Strings allows returning only the attributes whose content
// is a JSON string.
