type t

Connection

val connect : 
  id:string ->
  ?virtual_host:string ->
  ?port:int ->
  ?credentials:(string * string) ->
  ?heartbeat:int ->
  string ->
  t Thread.Deferred.t

Connect to an Amqp server.

connect ~id:"test" localhost connects to localhost using default guest credentials, with identity "test"

parameter id
an identifier of the connection used for tracing and debugging

parameter credentials
a tuple of username * password. The credentials are transmitted in plain text

parameter virtual_host
Named of the virtual host. Virtual must be defined on the amqp-server prior to connecting them. Default "/"

parameter port
The port to connect to

parameter heartbeat
Delay between heartbeats in seconds. Lower the number to detect connection loss faster.
If an error occurs an exception is raised. To capture and handle exceptions it is advised to detach a monitor Core.Async.Monitor and handle raised exceptions.
The most important exception is Connection_closed. As the connection is stateful (channels are tied to connections e.g), the connection cannot be re-established without redoing all initalization.

val connect_uri : id:string -> string -> t Thread.Deferred.t

Connect to amqp using an uri.

connect_uri ~id:"test" "amqp://localhost/" connects to amqp server on localhost using default port and default username/password.

The uri must be on the form: ampq://user:password@hostname:port/vhost?params. Currently only 'heartbeat_interval=<sec>' parameter is used.

val open_channel : 
  id:string ->
  'a Channel.confirms ->
  t ->
  'a Channel.t Thread.Deferred.t

Open a new channel.

parameter id
identifies the channel for tracing and debugging

val close : t -> unit Thread.Deferred.t

val on_closed : t -> unit Thread.Deferred.t

on_closed becomes ready when the connection has been closed.
