 * the client will spawn {@link ClientOptions#shardCount} shards. If set to `auto`, it will fetch the
 * recommended amount of shards from Discord and spawn that amount
 * @property {number} [shardCount=1] The total amount of shards used by all processes of this bot
 * (e.g. recommended shard count, shard count of the ShardingManager)
 * @property {number} [messageCacheMaxSize=200] Maximum number of messages to cache per channel
 * (-1 or Infinity for unlimited - don't do this without message sweeping, otherwise memory usage will climb
 * indefinitely)
 * @property {number} [messageCacheLifetime=0] How long a message should stay in the cache until it is considered
 * sweepable (in seconds, 0 for forever)
 * @property {number} [messageSweepInterval=0] How frequently to remove messages from the cache that are older than
 * the message cache lifetime (in seconds, 0 for never)
 * @property {MessageMentionOptions} [allowedMentions] Default value for {@link MessageOptions#allowedMentions}
 * @property {number} [invalidRequestWarningInterval=0] The number of invalid REST requests (those that return
 * 401, 403, or 429) in a 10 minute window between emitted warnings (0 for no warnings). That is, if set to 500,
 * warnings will be emitted at invalid request number 500, 1000, 1500, and so on.
 * @property {PartialType[]} [partials] Structures allowed to be partial. This means events can be emitted even when
 * they're missing all the data for a particular structure. See the "Partials" topic listed in the sidebar for some
 * important usage information, as partials require you to put checks in place when handling data.
 * @property {number} [restWsBridgeTimeout=5000] Maximum time permitted between REST responses and their
 * corresponding websocket events
 * @property {number} [restTimeOffset=500] Extra time in milliseconds to wait before continuing to make REST
 * requests (higher values will reduce rate-limiting errors on bad connections)
 * @property {number} [restRequestTimeout=15000] Time to wait before cancelling a REST request, in milliseconds
 * @property {number} [restSweepInterval=60] How frequently to delete inactive request buckets, in seconds
 * (or 0 for never)
 * @property {number} [restGlobalRateLimit=0] How many requests to allow sending per second (0 for unlimited, 50 for
 * the standard global limit used by Discord)
 * @property {string[]|RateLimitQueueFilter} [rejectOnRateLimit] Decides how rate limits and pre-emptive throttles
 * should be handled. If this option is an array containing the prefix of the request route (e.g. /channels to match any
 * route starting with /channels, such as /channels/222197033908436994/messages) or a function returning true, a
 * {@link RateLimitError} will be thrown. Otherwise the request will be queued for later
 * @property {number} [retryLimit=1] How many times to retry on 5XX errors (Infinity for indefinite amount of retries)
 * @property {PresenceData} [presence={}] Presence data to use upon login
 * @property {IntentsResolvable} intents Intents to enable for this connection
 * @property {WebsocketOptions} [ws] Options for the WebSocket
 * @property {HTTPOptions} [http] HTTP options
