/**
 * ThresholdRule contains the definition of a threshold. Threshold rules define
 * the triggering events used to generate a budget notification email. When a
 * threshold is crossed (spend exceeds the specified percentages of the
 * budget), budget alert emails are sent to the email recipients you specify
 * in the
 * [NotificationsRule](#notificationsrule).
 * Threshold rules also affect the fields included in the
 * [JSON data
 * object](https://cloud.google.com/billing/docs/how-to/budgets-programmatic-notifications#notification_format)
 * sent to a Pub/Sub topic.
 * Threshold rules are _required_ if using email notifications.
 * Threshold rules are _optional_ if only setting a
 * [`pubsubTopic` NotificationsRule](#NotificationsRule),
 * unless you want your JSON data object to include data about the thresholds
 * you set.
 * For more information, see
 * [set budget threshold rules and
 * actions](https://cloud.google.com/billing/docs/how-to/budgets#budget-actions).
