 * 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 {CacheFactory} [makeCache] Function to create a cache.
 * You can use your own function, or the {@link Options} class to customize the Collection used for the cache.
 * <warn>Overriding the cache used in `GuildManager`, `ChannelManager`, `GuildChannelManager`, `RoleManager`,
 * and `PermissionOverwriteManager` is unsupported and **will** break functionality</warn>

 * 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 "Partial Structures" topic on the
 * [guide](https://discordjs.guide/popular-topics/partials.html) for some
 * important usage information, as partials require you to put checks in place when handling data.

 * @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

 * (Infinity for an indefinite amount of retries)
 * @property {boolean} [failIfNotExists=true] Default value for {@link ReplyMessageOptions#failIfNotExists}
