AMQP.SelectiveConsumer (amqp v3.0.0) View Source

This is an Elixir reimplementation of :amqp_selective_consumer - source.

The module is used by default when you open a channel via AMQP.Channel.open/2 and allows you to end consumer processes via AMQP.Basic.consume/4 and receive messages from a queue.

Usually you don't have to pay attention to this module as the interaction would be made through AMQP.Channel.open/2, AMQP.Basic.consume/4, AMQP.Basic.return/2, AMQP.Confirm.register_handler/2 etc.

register_default_consumer(channel, consumer_pid)

Specs

register_default_consumer(AMQP.Channel.t(), pid()) :: :ok

Ported from :amqp_selective_consumer.register_default_consumer/2.

This function registers a default consumer with the channel.

A default consumer is used when a subscription is made via amqp_channel:call(ChannelPid, #'basic.consume'{}) (rather than {@module}:subscribe/3) and hence there is no consumer pid registered with the consumer tag. In this case, the relevant deliveries will be sent to the default consumer.
