Actor Effect

The Actor effect provides the following built-in operations, wired into the VM and runtime.

Operation	Signature	Description
Actor.link	link(target: Actor) -> Nil	Link the current actor to target; abnormal exits propagate to linked peers. Nil no-op outside an actor.
Actor.unlink	unlink(target: Actor) -> Nil	Remove the link between the current actor and target. Nil no-op outside an actor.
Actor.monitor	monitor(target: Actor) -> Nil	Monitor target from the current actor; a DOWN system message is delivered when it exits. Nil no-op outside an actor.
Actor.demonitor	demonitor(target: Actor) -> Nil	Stop the current actor’s monitor on target, so no DOWN message is delivered. Nil no-op outside an actor.
Actor.trap_exit	trap_exit(flag: Bool) -> Nil	Set the current actor’s trap_exits flag; when true, linked-peer exit signals arrive as system messages instead of killing it. Nil no-op outside an actor.
Actor.exit	exit(reason: Int | String) -> Nil	Self-exit the current actor; 0/“normal”, 1/“error”, 2/“kill” select the reason, anything else is custom. Nil no-op outside an actor.
Actor.register	register(name: String) -> Nil	Register the current actor under name in the local actor registry. Nil no-op outside an actor.
Actor.unregister	unregister(name: String) -> Nil	Remove name from the local actor registry.
Actor.whereis	whereis(name: String) -> Actor | Nil	Look up name in the local actor registry; returns the actor ref, or nil when the name is not registered.
Actor.set_priority	set_priority(level: Int) -> Nil	Set the current actor’s scheduling priority: 0=High, 1=Normal, 2=Low (any other value selects Normal). Ready High-priority actors are scheduled before Normal, Normal before Low; affects scheduling only, not message order. Nil no-op outside an actor.
