 * Act on user account cancellations.
 *
 * This hook is invoked from user_cancel() before a user account is canceled.
 * Depending on the account cancellation method, the module should either do
 * nothing, unpublish content, or anonymize content. See user_cancel_methods()
 * for the list of default account cancellation methods provided by User module.
 * Modules may add further methods via hook_user_cancel_methods_alter().
 *
 * This hook is NOT invoked for the 'user_cancel_delete' account cancellation
 * method. To react to that method, implement hook_ENTITY_TYPE_predelete() or
 * hook_ENTITY_TYPE_delete() for user entities instead.
 *
 * Expensive operations should be added to the global account cancellation batch
 * by using batch_set().
 *
 * @param array $edit
 *   The array of form values submitted by the user.
 * @param \Drupal\Core\Session\AccountInterface $account
 *   The user object on which the operation is being performed.
 * @param string $method
 *   The account cancellation method.
 *
 * @see user_cancel_methods()
 * @see hook_user_cancel_methods_alter()

 * button form elements by user_cancel_methods() after this hook is invoked.
 * The following properties can be defined for each method:
 * - title: The radio button's title.
 * - description: (optional) A description to display on the confirmation form
 *   if the user is not allowed to select the account cancellation method. The
 *   description is NOT used for the radio button, but instead should provide
 *   additional explanation to the user seeking to cancel their account.
 * - access: (optional) A boolean value indicating whether the user can access
 *   a method. If 'access' is defined, the method cannot be configured as
 *   default method.
 *
 * @param array $methods
 *   An array containing user account cancellation methods, keyed by method id.

 * @see user_cancel_methods()
