LavinMQ::MQTT::Subscriber
Entry type of a vhost's SubscriptionTree. The tree's entry hashes compare by identity, so including types must be reference types.
Instance methods
Called once per matching filter when an MQTT message is published.
ctx is the publishing client's scratch state, reset per publish, so a
subscriber matched by several filters can tell the calls apart from a
new publish. Returns true if the message was accepted by at least one
receiver.
