\n\nClasses\n-------\n\n### [PublisherClient](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherClient)\n\nEventarc processes events generated by an event provider and delivers them to a subscriber.\n\n### [PublisherConnection](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection)\n\nThe [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection) object for [`PublisherClient`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherClient).\n\n### [PublisherConnectionIdempotencyPolicy](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnectionIdempotencyPolicy)\n\n### [PublisherLimitedErrorCountRetryPolicy](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherLimitedErrorCountRetryPolicy)\n\nA retry policy for [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection) based on counting errors.\n\n### [PublisherLimitedTimeRetryPolicy](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherLimitedTimeRetryPolicy)\n\nA retry policy for [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection) based on elapsed time.\n\n### [PublisherRetryPolicy](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherRetryPolicy)\n\nThe retry policy for [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection).\n\nStructs\n-------\n\n### [PublisherBackoffPolicyOption](/cpp/docs/reference/eventarc/latest/structgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherBackoffPolicyOption)\n\nUse with [`google::cloud::Options`](https://cloud.google.com/cpp/docs/reference/common/latest/classgoogle_1_1cloud_1_1Options.html) to configure the backoff policy.\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### MakePublisherConnection(Options)\n\nA factory function to construct an object of type [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection). \nThe returned connection object should not be used directly; instead it should be passed as an argument to the constructor of [PublisherClient](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherClient).\n\nThe optional `options` argument may be used to configure aspects of the returned [`PublisherConnection`](/cpp/docs/reference/eventarc/latest/classgoogle_1_1cloud_1_1eventarc__publishing__v1_1_1PublisherConnection). 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::eventarc_publishing_v1::PublisherPolicyOptionList`](about:invalid#zCSafez)\n\n| **Note:** Unexpected options will be ignored.
