Function amqpr_api::queue::declare::declare_queue_wait

pub fn declare_queue_wait<In, Out, E>(
    income: In, 
    outcome: Out, 
    channel_id: u16, 
    option: DeclareQueueOption
) -> QueueDeclaredWait<In, Out> where
    In: Stream<Error = E>,

    Out: Sink<SinkItem = Frame, SinkError = E>,
    E: From<Error>, 

Declare a queue synchronously. That means we will wait to receive Declare-Ok method after send Declare method. If you want not to wait receiving, you should use declare_queue instead. This function ignores is_not_wait flag of option.
