// `Endpoint` describes a network endpoint that serves a set of APIs.
// A service may expose any number of endpoints, and all endpoints share the
// same service configuration, such as quota configuration and monitoring
// configuration.

// Example service configuration:
//
//     name: library-example.googleapis.com
//     endpoints:
//       # Below entry makes 'google.example.library.v1.Library'
//       # API be served from endpoint address library-example.googleapis.com.
//       # It also allows HTTP OPTIONS calls to be passed to the backend, for
//       # it to decide whether the subsequent cross-origin request is
//       # allowed to proceed.
//     - name: library-example.googleapis.com
