  ?durable:bool ->

  ?arguments:Amqp_client_lib.Types.table ->

  t Thread.Deferred.t

Declare a queue

val get : no_ack:bool -> _ Channel.t -> t -> Message.t option Thread.Deferred.t

Get a single message from the queue. The function automatically handles ack.

If no_ack is false (default), the message is requsted with expicit ack and the caller is responsible for ack'ing or rejecting the message.

val publish : 
  'a Channel.t ->
  t ->
  ?mandatory:bool ->
  Message.message ->
  'a Thread.Deferred.t

Publish a message directly to a queue

val consume : 
  id:string ->
  ?no_local:bool ->
  ?no_ack:bool ->
  ?exclusive:bool ->
  'a Channel.t ->
  t ->
  ('a consumer * Message.t Thread.Pipe.Reader.t) Thread.Deferred.t

Setup consumption of a queue. Remember to ack messages.

All messages are processed concurrently. To limit number of concurrent processes, set the prefetch threshold.

val cancel : _ consumer -> unit Thread.Deferred.t

Cancel consumption.

val bind : _ Channel.t -> t -> 'b Exchange.t -> 'b -> unit Thread.Deferred.t

Bind a queue to an exchange. Messages posted on the exchange which match the routing key (and optionally match the headers) will be routed to the queue

val unbind : _ Channel.t -> t -> 'b Exchange.t -> 'b -> unit Thread.Deferred.t

Remove a binding from an exchange to a queue

val purge : _ Channel.t -> t -> unit Thread.Deferred.t

Purge all messages on a queue

val delete : 
  ?if_unused:bool ->
  ?if_empty:bool ->
  _ Channel.t ->
  t ->
  unit Thread.Deferred.t

Delete a queue

val name : t -> string

Name of the queue
