Functions

Function	Summary
emit	Fan payload out to every subscriber of channel, excluding the emitter (no self-delivery — kills the trivial feedback loop).
subscribe	Deliver future emits on channel to this mod’s server-api.on-signal.

emit

emit: func(channel: string, payload: list<u8>) -> result<_, string>;

Fan payload out to every subscriber of channel, excluding the emitter (no self-delivery — kills the trivial feedback loop). Delivery is reliable in the normal case and sheds loudly per overloaded subscriber; it never stalls the simulation. Emits fired while server mods are still loading are queued and flushed once all of them are up, so an init-time emit cannot race another mod’s init-time subscribe. Errors on an empty or oversized channel name, an oversized payload, or an overflow of that pre-load queue.

subscribe

subscribe: func(channel: string) -> result<_, string>;

Deliver future emits on channel to this mod’s server-api.on-signal. Idempotent; no replay — a signal is a moment, a late subscriber misses history by design. Subscriptions die with the mod. Errors on an empty or oversized channel name.
