[BudgetServiceClient](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceClient)\n\nBudgetService stores Cloud Billing budgets, which define a budget plan and rules to execute as we track spend against that plan.\n\n### [BudgetServiceConnection](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection)\n\nThe [`BudgetServiceConnection`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection) object for [`BudgetServiceClient`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceClient).\n\n### [BudgetServiceConnectionIdempotencyPolicy](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnectionIdempotencyPolicy)\n\n### [BudgetServiceLimitedErrorCountRetryPolicy](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceLimitedErrorCountRetryPolicy)\n\nA retry policy for [`BudgetServiceConnection`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection) based on counting errors.\n\n### [BudgetServiceLimitedTimeRetryPolicy](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceLimitedTimeRetryPolicy)\n\nA retry policy for [`BudgetServiceConnection`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection) based on elapsed time.\n\n### [BudgetServiceRetryPolicy](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceRetryPolicy)\n\nThe retry policy for

[`google::cloud::Options`](https://cloud.google.com/cpp/docs/reference/common/latest/classgoogle_1_1cloud_1_1Options.html) to configure which operations are retried.\n\n###

[`google::cloud::Options`](https://cloud.google.com/cpp/docs/reference/common/latest/classgoogle_1_1cloud_1_1Options.html) to configure the retry policy.\n\nFunctions\n---------\n\n### MakeBudgetServiceConnection(Options)\n\nA factory function to construct an object of type [`BudgetServiceConnection`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection). \nThe returned connection object should not be used directly; instead it should be passed as an argument to the constructor of [BudgetServiceClient](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceClient).\n\nThe optional `options` argument may be used to configure aspects of the returned [`BudgetServiceConnection`](/cpp/docs/reference/billing/latest/classgoogle_1_1cloud_1_1billing__budgets__v1_1_1BudgetServiceConnection). Expected options are any of the types in the following option lists:\n\n- [`google::cloud::CommonOptionList`](https://cloud.google.com/cpp/docs/reference/common/latest/namespacegoogle_1_1cloud.html)\n- [`google::cloud::GrpcOptionList`](https://cloud.google.com/cpp/docs/reference/common/latest/namespacegoogle_1_1cloud.html)\n- [`google::cloud::UnifiedCredentialsOptionList`](about:invalid#zCSafez)\n- [`google::cloud::billing_budgets_v1::BudgetServicePolicyOptionList`](about:invalid#zCSafez)\n\n| **Note:** Unexpected options will be ignored. To log unexpected options instead, set `GOOGLE_CLOUD_CPP_ENABLE_CLOG=yes` in the environment.\n\n### MakeDefaultBudgetServiceConnectionIdempotencyPolicy()"]]
