Struct SubscribeFuture 

pub struct SubscribeFuture {
    dispatch: DispatchState,
    queued_rx: Receiver<Result<(), Error>>,
    completion_rx: Receiver<Result<Vec<ReasonCode>, Error>>,
}
Expand description

A lazy future returned by SubscribeBuilder::send.

Awaiting this future drives the SUBSCRIBE packet to the broker and resolves with the SUBACK reason codes. Convert to a QueuedSubscribeFuture via queued to resolve as soon as the subscription is recorded locally.

Implementations§

§

impl SubscribeFuture

pub fn queued(self) -> QueuedSubscribeFuture ⓘ

Converts this future into a QueuedSubscribeFuture that resolves as soon as the subscription is recorded locally, without waiting for SUBACK.
