std::link_monitor — Hew Standard Library

Actor monitor / link handle helpers.

Import std::link_monitor when you want to name MonitorRef or LinkError explicitly. The monitor(actor) builtin returns MonitorRef; the link(actor) builtin returns Result<(), LinkError>.

v0.5 link/monitor builtins return through the Cluster 2 composite-return spine, which lands in v0.6. The runtime symbols exist (hew_actor_link, hew_actor_monitor), but the user-source surface fails closed today. See commit 1698840f for the explicit deferral.

Enum `LinkError`

Error returned by link(handle).

AlreadyLinked is an idempotent non-fatal condition — callers may treat it as Ok(()). TargetDead is returned when the target actor has already exited; the caller's exit handler will fire immediately.
