Detailed Description

template<class Object>
class mbgl::ActorRef< Object >

An ActorRef<O> is a non-owning, weak reference to an actor of type O. You can send it messages just like an Actor<O>. It's a value object: safe to copy and pass between actors via messages.

An ActorRef<O> does not extend the lifetime of the corresponding Actor<O>. That's determined entirely by whichever object owns the Actor<O> – the actor's "supervisor".

It's safe for a Ref to outlive its Actor – the reference is "weak", and does not extend the lifetime of the owning Actor, and sending a message to a Ref whose Actor has died is a no-op. (In the future, a dead-letters queue or log may be implemented.)
