Struct StorageRecord 

pub struct StorageRecord {
    pub id: String,
    pub pipeline_id: String,
    pub node_name: String,
    pub data: Value,
    pub metadata: HashMap<String, String>,
    pub timestamp_ms: u64,
}

A single result record produced by a pipeline node.

Example

use stygian_graph::ports::storage::StorageRecord;
use serde_json::json;

let r = StorageRecord::new("pipe-1", "fetch", json!({"url": "https://example.com"}));
assert_eq!(r.pipeline_id, "pipe-1");
assert_eq!(r.node_name,   "fetch");

Fields

id: String

Unique record ID (UUID v4)

pipeline_id: String

Pipeline this record belongs to

node_name: String

Graph node that produced this record

data: Value

Extracted data payload

metadata: HashMap<String, String>

Optional key-value metadata (headers, status code, …)

timestamp_ms: u64

Unix timestamp of when this record was created (milliseconds)

Implementations

impl StorageRecord

pub fn new(pipeline_id: &str, node_name: &str, data: Value) -> Self

Construct a new record with a fresh UUID and current timestamp.

Example

use stygian_graph::ports::storage::StorageRecord;
use serde_json::json;

let r = StorageRecord::new("p", "n", json!(null));
assert!(!r.id.is_empty());
assert!(r.timestamp_ms > 0);

pub fn with_metadata(self, key: &str, value: &str) -> Self

Attach metadata key-value pairs.

Example

use stygian_graph::ports::storage::StorageRecord;
use serde_json::json;

let r = StorageRecord::new("p", "n", json!(null))
    .with_metadata("status", "200");
assert_eq!(r.metadata["status"], "200");
