/**
 * Check whether a given peer ID can be used to actually
 * interact with the Telegram API.
 * This method checks the internal peers cache for the given
 * input peer, and returns `true` if it is available there.
 *
 * You can think of this method as a stripped down version of
 * {@link resolvePeer}, which only returns `true` or `false`.
 *
 * > **Note:** This method works offline and never sends any requests.
 * > This means that when passing a username or phone number, it will
 * > only return `true` if the user with that username/phone number
 * > is cached in the storage, and will not try to resolve the peer by calling the API,
 * > which *may* lead to false negatives.
