Struct Node 

pub struct Node {
    pub key: String,
    pub kind: NodeKind,
    pub name: String,
    pub path: Option<String>,
    pub lang: Option<String>,
    pub blob_hash: Option<String>,
    pub span: Option<Span>,
    pub meta: Value,
}

A node in the knowledge graph.

Node::key is the deterministic natural identity used for upserts (e.g. sym:rust:src/lib.rs#Store); the database row id is an internal detail.

Fields

key: String

Deterministic, unique natural key.

kind: NodeKind

The kind of thing this node represents.

name: String

Human-facing name (need not be unique).

path: Option<String>

Repository-relative source path, if any.

lang: Option<String>

Language token (e.g. rust), if applicable.

blob_hash: Option<String>

Git blob hash this node was extracted from, if applicable.

span: Option<Span>

Byte span within the source blob, if applicable.

meta: Value

Arbitrary structured metadata.

Implementations

impl Node

pub fn new( key: impl Into<String>, kind: NodeKind, name: impl Into<String>, ) -> Self
