Struct GraphNode 

pub struct GraphNode {
    pub id: NodeId,
    pub node_type: NodeType,
    pub external_id: String,
    pub label: String,
    pub features: Vec<f64>,
    pub categorical_features: HashMap<String, String>,
    pub properties: HashMap<String, NodeProperty>,
    pub labels: Vec<String>,
    pub is_anomaly: bool,
    pub anomaly_type: Option<String>,
}

A node in the graph.

Fields

id: NodeId

Unique node ID.

node_type: NodeType

Node type.

external_id: String

External ID (e.g., account code, vendor ID).

label: String

Node label for display.

features: Vec<f64>

Numeric features for ML.

categorical_features: HashMap<String, String>

Categorical features (will be one-hot encoded).

properties: HashMap<String, NodeProperty>

Node properties.

labels: Vec<String>

Labels for supervised learning.

is_anomaly: bool

Is this node an anomaly?

anomaly_type: Option<String>

Anomaly type if anomalous.

Implementations

impl GraphNode

pub fn new( id: NodeId, node_type: NodeType, external_id: String, label: String, ) -> Self

Creates a new graph node.

pub fn with_feature(self, value: f64) -> Self

Adds a numeric feature.

pub fn with_features(self, values: Vec<f64>) -> Self

Adds multiple numeric features.

pub fn with_categorical(self, name: &str, value: &str) -> Self

Adds a categorical feature.

pub fn with_property(self, name: &str, value: NodeProperty) -> Self

Adds a property.

pub fn as_anomaly(self, anomaly_type: &str) -> Self

Marks the node as anomalous.

pub fn with_label(self, label: &str) -> Self

Adds a label.

pub fn feature_dim(&self) -> usize

Returns the feature vector dimension.

pub fn from_entity(id: NodeId, entity: &dyn ToNodeProperties) -> Self

Create a graph node from any type implementing ToNodeProperties.

This bridges the domain model structs (with ToNodeProperties) to the graph export pipeline by converting all typed properties into NodeProperty values.

Trait Implementations

impl Clone for GraphNode

fn clone(&self) -> GraphNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GraphNode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for GraphNode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
