async fn check( &self, request: Request<HealthCheckRequest>, ) -> Result<Response<HealthCheckResponse>, Status>

Check gets the health of the specified service. If the requested service is unknown, the call will fail with status NOT_FOUND. If the caller does not specify a service name, the server should respond with its overall health status.

async fn list( &self, _request: Request<HealthListRequest>, ) -> Result<Response<HealthListResponse>, Status>

List provides a non-atomic snapshot of the health of all the available services.

async fn watch( &self, request: Request<HealthCheckRequest>, ) -> Result<Response<<HealthService as Health>::WatchStream>, Status>

Performs a watch for the serving status of the requested service. The server will immediately send back a message indicating the current serving status. It will then subsequently send a new message whenever the service’s serving status changes.
