Module remoc::robs::hash_set

Available on crate feature robs only.

Observable hash set.

This provides a locally and remotely observable hash set. The observable hash set sends a change event each time a change is performed on it. The resulting event stream can either be processed event-wise or used to build a mirrored hash set.

Changes are sent using a remote broadcast channel, thus subscribers cannot block the observed hash set and are shed when their event buffer exceeds a configurable size.

Basic use

Create a ObservableHashSet and obtain a subscription to it using ObservableHashSet::subscribe. Send this subscription to a remote endpoint via a remote channel and call HashSetSubscription::mirror on the remote endpoint to obtain a live mirror of the observed hash set or process each change event individually using HashSetSubscription::recv.
