///
/// # Configuration
///
/// To configure `QuotaController` use the `with_*` methods in the type returned
/// by [builder()][QuotaController::builder]. The default configuration should
/// work for most applications. Common configuration changes include
///
/// * [with_endpoint()]: by default this client uses the global default endpoint
///   (`https://servicecontrol.googleapis.com`). Applications using regional
///   endpoints or running in restricted networks (e.g. a network configured
///   with [Private Google Access with VPC Service Controls]) may want to
///   override this default.
/// * [with_credentials()]: by default this client uses
///   [Application Default Credentials]. Applications using custom
///   authentication may need to override this default.
///
/// [with_endpoint()]: super::builder::quota_controller::ClientBuilder::with_endpoint
