Interface SubOpts<T>

An optional function that will handle messages. Typically, messages are processed via an async iterator on the subscription. If this option is provided, messages are processed by the specified function.

Param: err

Param: msg

Optional maximum number of messages to deliver to the subscription before it is auto-unsubscribed.

Optional queue name (subscriptions on the same subject that use queues are horizontally load balanced when part of the same queue).

Optional maximum number of milliseconds before a timer raises an error. This useful to monitor a subscription that is expected to yield messages. The timer is cancelled when the first message is received by the subscription.
