Expand description

v1.6.0 D4 — dual-mode listen.

channel_is_ref = true ⇒ channel is the name of a declared ChannelDefinition (canonical v1.6.0 form). false ⇒ legacy string topic (deprecated; type checker emits a warning).

Fields§

§channel: String§channel_is_ref: bool§event_alias: String§body: Vec<FlowStep>

v2.4.0 — the handler body: real flow-steps executed on each event / scheduled tick. Pre-v2.4.0 the { … } block was skip_braced_block’d (the listener was inert); now it is parsed so a daemon can run logic (e.g. run <Flow>(…)) per trigger. Empty for a bodyless listen.
