Support Null?
vorner opened this issue · comments
It could sometimes be desirable to represent empty state. eg. some form of NULL. On the other hand, every user would then need to explicitly handle the NULL case even if it doesn't happen for them. Is it worth?
You could make it generic, ie. Swap<T: RefCounted> and have ArcSwap be an alias, and also implement RefCounted for Option<Arc<T>>
That's actually a nice idea. And it could be also implemented (under a feature) for all these Arcs from other crates without weak counts, etc.
Implemented and released as part of 0.2
