/**
* Returns a renderable array for the value of a single field in an entity.
*
* To integrate with in-place field editing when a non-standard render pipeline
* is used (FieldItemListInterface::view() is not sufficient to render back the
* field following in-place editing in the exact way it was displayed
* originally), implement this hook.
*
* Edit module integrates with HTML elements with data-edit-field-id attributes.
* For example:
* data-edit-field-id="node/1/<field-name>/und/<module-name>-<custom-id>"
* After the editing is complete, this hook is invoked on the module with
* the custom render pipeline identifier (last part of data-edit-field-id) to
* re-render the field. Use the same logic used when rendering the field for
* the original display.
*
* The implementation should take care of invoking the prepare_view steps. It
* should also respect field access permissions.
*
* @param \Drupal\Core\Entity\EntityInterface $entity
* The entity containing the field to display.
* @param string $field_name
* The name of the field to display.
* @param string $view_mode_id
* View mode ID for the custom render pipeline this field view was destined
* for. This is not a regular view mode ID for the Entity/Field API render
* pipeline and is provided by the renderer module instead. An example could
* be Views' render pipeline. In the example of Views, the view mode ID would
* probably contain the View's ID, display and the row index. Views would
* know the internal structure of this ID. The only structure imposed on this
* ID is that it contains dash separated values and the first value is the
* module name. Only that module's hook implementation will be invoked. Eg.
* 'views-...-...'.
* @param string $langcode
* (Optional) The language code the field values are to be shown in.
*
* @return
* A renderable array for the field value.
*
* @see \Drupal\Core\Field\FieldItemListInterface::view()
