Description
We're going to need to store references to the
Context
on both channels (for access to subscriptions) and sinks (for dynamic subscription management and unregister-on-drop), so we're going to want anArc
. Since the context holdsArc
references to channels and sinks, channels and sinks will holdWeak
references back to the context.
