AMQPHelpers.RPC (AMQP Helpers v1.3.0)

Link to this function

call(adapter \\ Adapter, connection, exchange, routing_key, payload, options \\ [])

Specs

Executes a remote procedure call.

This function sends the given messages and waits for a response using Direct Reply-to.

This function uses a Task internally to wait for responses. This means all the caveats and OTP compatibility Task issues apply here too. Check call_nolink/7 for more information.

Link to this function

call_nolink(adapter \\ Adapter, supervisor, connection, exchange, routing_key, payload, options \\ [])

Specs

Executes a remote procedure call without linking to the calling process.

Like call/6 but it does not link the waiting process to the calling process. Check Task.Supervisor for more information.
