/**
 * Service Description: Service for ingesting and querying logs.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * ```
 * $loggingServiceV2Client = new LoggingServiceV2Client();
 * try {
 *     $formattedLogName = $loggingServiceV2Client->logName('[PROJECT]', '[LOG]');
 *     $loggingServiceV2Client->deleteLog($formattedLogName);
 * } finally {
 *     $loggingServiceV2Client->close();
 * }
 * ```
 *
 * Many parameters require resource names to be formatted in a particular way. To
 * assist with these names, this class includes a format method for each type of
 * name, and additionally a parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.

     *           Optional. Default labels that are added to the `labels` field of all log
     *           entries in `entries`. If a log entry already has a label with the same key
     *           as a label in this parameter, then the log entry's label is not changed.
     *           See [LogEntry][google.logging.v2.LogEntry].
     *     @type bool $partialSuccess
     *           Optional. Whether valid entries should be written even if some other
     *           entries fail due to INVALID_ARGUMENT or PERMISSION_DENIED errors. If any
     *           entry is not written, then the response status is the error associated
     *           with one of the failed entries and the response includes error details
     *           keyed by the entries' zero-based index in the `entries.write` method.
     *     @type bool $dryRun
     *           Optional. If true, the request should expect normal response, but the
     *           entries won't be persisted nor exported. Useful for checking whether the
     *           logging API endpoints are working properly before sending valuable data.
     *     @type RetrySettings|array $retrySettings
     *           Retry settings to use for this call. Can be a {@see RetrySettings} object, or an
     *           associative array of retry settings parameters. See the documentation on
     *           {@see RetrySettings} for example usage.
