Enum ForestEvent 

enum ForestEvent {
    NodeState {
        plan_id: String,
        node_state: Box<RtdlNodeState>,
    },
    PlanDone {
        plan_id: String,
        results: Vec<RtdlNodeState>,
        any_failed: bool,
        canceled: bool,
    },
}

Events fed from per-tree driver tasks back to the supervisor loop. One drive_plan task runs per dispatched tree and streams these.

Variants

NodeState

A node changed state — forwarded for live visualisation. Carries the originating tree’s plan_id. The state is boxed because it is much larger than the other variant’s payload.

Fields

plan_id: String

node_state: Box<RtdlNodeState>

PlanDone

A tree finished (or its Execute stream ended/errored). Carries one full RtdlNodeState record for every node that reached a terminal state (leaf and non-leaf), collected from the tree.

Fields

plan_id: String

results: Vec<RtdlNodeState>

any_failed: bool

canceled: bool

True when this tree ended because it was canceled (a node reached CANCELED), as opposed to running to natural success/failure. A cancellation fulfils a prior decision and carries no new info, so the supervisor must NOT trigger a fresh planning round for it — otherwise “cancel old plan → PlanDone → replan → model re-cancels” becomes a self-sustaining storm with monotonically growing plan ids.
