Struct Node 

pub struct Node {
    pub id: String,
    pub service: String,
    pub config: Value,
    pub metadata: Value,
}

A node in the scraping pipeline graph

Represents a single operation (HTTP fetch, AI extraction, transformation, etc.)

Example

use stygian_graph::domain::graph::Node;
use serde_json::json;

let node = Node::new(
    "fetch_homepage",
    "http",
    json!({"url": "https://example.com", "method": "GET"})
);

Fields

id: String

Unique identifier for this node

service: String

Service type (e.g., "http", "ai_extract", "browser")

config: Value

Node-specific configuration

metadata: Value

Optional node metadata

Implementations

impl Node

pub fn new( id: impl Into<String>, service: impl Into<String>, config: Value, ) -> Self

Create a new node

Example

use stygian_graph::domain::graph::Node;
use serde_json::json;

let node = Node::new("fetch", "http", json!({"url": "https://example.com"}));
assert_eq!(node.id, "fetch");
assert_eq!(node.service, "http");

pub fn with_metadata( id: impl Into<String>, service: impl Into<String>, config: Value, metadata: Value, ) -> Self

Create a new node with metadata

pub fn validate(&self) -> Result<(), StygianError>

Validate the node configuration

Errors

Returns GraphError::InvalidEdge if the node has an empty ID or service type.
