AMQP

The AMQP binding. The emitted member is amqp, and every object carries bindingVersion: 0.3.0.

@amqpChannel

extern dec amqpChannel(
  target: Interface | Namespace,
  config: valueof AsyncAPIAmqpChannelBinding
);

Field	Type	Required
is	string	no
exchange	AsyncAPIAmqpExchange	no
queue	AsyncAPIAmqpQueue	no

Apply it to the interface or namespace that carries @channel or @dynamicChannel.

WARNING

is is a TypeSpec keyword. Write the field name in backticks: `is`: "routingKey". The emitted member is still is.

is is queue or routingKey. exchange.type is one of topic, direct, fanout, default and headers. A name of an exchange or a queue is at most 255 characters.

The member covers AMQP 0-9-1. AsyncAPI defines a separate amqp1 binding for AMQP 1.0, and this library does not emit it.

@amqpChannel(#{
  `is`: "routingKey",
  exchange: #{ name: "events", type: "topic", durable: true }
})
@channel("events.created")
interface EventChannel {}

@amqpOperation

extern dec amqpOperation(target: Operation, config: valueof AsyncAPIAmqpOperationBinding);

Field	Type	Required
expiration	int32	no
userId	string	no
cc	string[]	no
priority	int32	no
deliveryMode	int32	no
mandatory	boolean	no
bcc	string[]	no
timestamp	boolean	no
ack	boolean	no

Apply it to an operation that carries @send or @receive.

deliveryMode is 1 for transient and 2 for persistent. expiration is a number of milliseconds, so it is never negative.

The emitted field order follows the specification, not the order the fields were written.

@amqpMessage

extern dec amqpMessage(target: Model, config: valueof AsyncAPIAmqpMessageBinding);

Field	Type	Required
contentEncoding	string	no
messageType	string	no

Apply it to a model that also carries @message. AMQP states no set of values for either field.
