/**
 * A log is a named collection of entries, each entry representing a timestamped
 * event. Logs can be produced by Google Cloud Platform services, by third-party
 * services, or by your applications. For example, the log `apache-access` is
 * produced by the Apache Web Server, but the log
 * `compute.googleapis.com/activity_log` is produced by Google Compute Engine.
 *
 * See {@link https://cloud.google.com/logging/docs/basic-concepts#logs|Introduction to Logs}
 *
 * @class
 *
 * @param {Logging} logging {@link Logging} instance.
 * @param {string} name Name of the log.
 * @param {object} [options] Configuration object.
 * @param {boolean} [options.removeCircular] Replace circular references in
 *     logged objects with a string value, `[Circular]`. (Default: false)
 * @param {number} [options.maxEntrySize] A max entry size
 * @param {string[]} [options.jsonFieldsToTruncate] A list of JSON properties at the given full path to be truncated.
 *     Received values will be prepended to predefined list in the order received and duplicates discarded.
 * @param {ApiResponseCallback} [options.defaultWriteDeleteCallback] A default global callback to be used for {@link Log#write}
 *     and {@link Log#delete} APIs when {@link ApiResponseCallback} callback was not supplied by caller in function parameters.
 *     Note that {@link LogOptions#defaultWriteDeleteCallback} is useful when {@link Log#write} and {@link Log#delete} APIs are called
 *     without `await` and without callback added explicitly to every call - this way {@link LogOptions#defaultWriteDeleteCallback}
 *     can serve as global callback handler, which for example could be used to catch all errors and eliminate crashes.
 * @param {boolean} [options.partialSuccess] Global flag indicating Whether a batch's valid entries should be written even if
 *     some other entry failed due to errors. Default is true.
 *     See {@link https://cloud.google.com/logging/docs/reference/v2/rest/v2/entries/write#body.request_body.FIELDS.partial_success|partialSuccess} for more info.
 * @example
 * ```
 * import {Logging} from '@google-cloud/logging';
 * import {LogOptions} from '@google-cloud/logging/build/src/log';
 * const options: LogOptions = {
 *   maxEntrySize: 256,
 *   jsonFieldsToTruncate: [
 *     'jsonPayload.fields.metadata.structValue.fields.custom.stringValue',
 *   ],
 *   defaultWriteDeleteCallback: (err: any) => {
 *     if (err) {
 *       console.log('Error: ' + err);
 *     }
