rill-core-actor 0.5.0-beta.5

Actor model infrastructure for the Rill ecosystem
Documentation

rill-core-actor

Minimal, domain-agnostic actor model for lock-free message passing.

Philosophy

This is not Pekko, not Erlang/OTP. No supervision, clustering, persistence, streaming, or Kafka connectors.

Four types, two of which are optional:

Type Purpose Required?
ActorRef<M> Thread-safe handle for sending messages yes
ActorCell Trait: "I can receive and process messages" yes
MessageDispatcher<M> ActorRef + dead letters no
ActorSystem<M> Named mailbox registry with routing no

Everything else lives upstream (rill-patchbay, Runtime with its lifecycle).

Usage

use rill_core_actor::ActorRef;

let (ar, mailbox) = ActorRef::<String>::new_pair();
ar.send("hello".into());
assert_eq!(mailbox.pop(), Some("hello".into()));

RT-safe?

send() — yes (lock-free, bounded queue).
receive() — depends on the calling thread (the actor decides).
route() / broadcast() — soft-RT only.

How not to grow into Pekko

Rule: if new functionality needs more than 10 lines in ActorRef or ActorSystem, it probably does not belong here. Move it upstream (rill-patchbay, rill-adrift).
