Struct NodeDescribe 

pub struct NodeDescribe {
    pub type: NodeTypeStr,
    pub status: NodeStatus,
    pub value: Option<HandleId>,
    pub deps: Vec<String>,
    pub meta: Option<Value>,
}

Per-node descriptor.

Fields

type: NodeTypeStr

"state" / "derived" / "dynamic" / "producer". Producer-vs-state inference: a state node with no fn-id but has_fired_once=true may stem from a producer pattern; the rust-side classifier just reports kind directly. (Producer inference is a binding-side concern — see canonical §3.6.1.)

status: NodeStatus

Lifecycle status (canonical Appendix B enum).

value: Option<HandleId>

Raw handle of the node’s current cache. None when the cache is sentinel (NO_HANDLE). Bindings render to T before surfacing to end users.

deps: Vec<String>

Dep names in declaration order. Unnamed deps surface as _anon_<NodeId> to keep the output lossless without elevating Core-only nodes into the namespace.

meta: Option<Value>

Free-form metadata per canonical Appendix B (e.g. { "description": "...", "type": "integer", "range": [1, 10] }). Always None in this slice — the metadata-storage primitive on Core hasn’t shipped yet. Reserved as Option<serde_json::Value> so the JSON shape stays forward-compatible (omitted via skip_serializing_if when None to keep current outputs slim).

Trait Implementations

impl Serialize for NodeDescribe

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
