Make nats::subscription::IntoIter public

[lkral-navmatix]

Use Case:

I believe it is currently not possible to store blocking::Unblock<nats::subscription::IntoIter> in a struct as IntoIter is not exported publicly. Boxing in this case can't be used as blocking::Unblock would not implement Stream.

Proposed Change:

Make nats::subscription::IntoIter publicly accessible.

Who Benefits From The Change(s)?

Anybody that would like to store return type of blocking::Unblock::new(subscription.into_iter()) in a struct for later use.

Alternative Approaches

I am not currently aware of different approach to solve this

We should resolve the Voldemort types. However, we've been working on a real async crate: published as async-nats where subscribers are streams. Still early but, it is a lot more performant than the asynk wrapper.

Closing as stale.
