Attribute Macro export

#[export]

Exports handlers for this actor. The set of exported handlers determine the messages that may be sent to remote references of the actor ([hyperaxtor::ActorRef]). Only messages that implement [hyperactor::RemoteMessage] may be exported.

Additionally, an exported actor may be remotely spawned, indicated by spawn = true. Such actors must also ensure that their parameter type implements [hyperactor::RemoteMessage].

Example

In the following example, MyActor can be spawned remotely. It also has exports handlers for two message types, MyMessage and MyOtherMessage. Consequently, ActorRefs of the actor’s type may dispatch messages of these types.

#[export(
    spawn = true,
    handlers = [
        MyMessage,
        MyOtherMessage,
    ],
)]
struct MyActor {}
