/**
 * Service Description: BudgetService stores Cloud Billing budgets, which define a
 * budget plan and rules to execute as we track spend against that plan.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods.
 *
 * Many parameters require resource names to be formatted in a particular way. To
 * assist with these names, this class includes a format method for each type of
 * name, and additionally a parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.
 *
 * This class is currently experimental and may be subject to changes. See {@see
 * \Google\Cloud\Billing\Budgets\V1\BudgetServiceClient} for the stable
 * implementation
