Struct NodeSpec 

pub struct NodeSpec {
    pub op: String,
    pub fields: Map<String, Value>,
}

One node entry. op selects the implementation; remaining fields are op-specific and are validated by the NodeFactory registered for op.

Fields

op: String

fields: Map<String, Value>

All remaining fields. Scalars are literals (color, number, bool); strings that begin with @ are node references, strings that begin with $ are param references.

Implementations

impl NodeSpec

pub fn refs(&self) -> Vec<String>

Every @name this node’s fields mention, in traversal order and with duplicates kept.

The scan is over the raw JSON rather than a per-op field list, because that is what the wiring is: any string field may carry a reference, at any depth, including inside an expression array. A name here has not been resolved — it may be a node, a source, or nothing at all.

Trait Implementations

impl Clone for NodeSpec

fn clone(&self) -> NodeSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
