hare v0.2.2 Hare.Context.Action.DeclareExchange
This module implements a Hare.Context.Action
behaviour to
declare an exchange on the AMQP server.
Config
Configuration must be a Keyword.t
with the following fields:
:name
- the name of the exchange:type
- (defaults to:direct
) the type of the exchange:opts
- (defaults to[]
) the options to be given to the adapter:export_as
- (defaults tonil
) the key to export the declared exchange to
The :export_as
config allows the action to export a Hare.Core.Exchange
struct to be used later by other steps (for example: to bind a queue to it)
alias Hare.Context.Action.DeclareExchange
config = [name: "foo",
type: :fanout,
opts: [durable: true],
export_as: :ex]
exports = %{}
DeclareExchange.run(chan, config, exports)
# => {:ok, nil, %{ex: %Hare.Core.Exchange{chan: chan, name: "foo"}}}
