Struct StoredNode 

pub struct StoredNode {
    pub id: String,
    pub label: String,
    pub node_type: String,
    pub label_id: LabelId,
    pub flags: u8,
    pub out_edge_count: u32,

    pub slot: u16,
    pub table_ref: Option<TableRef>,
    pub vector_ref: Option<(String, u64)>,
}

A graph node stored on disk

Fields

id: String

label: String

node_type: String

Canonical category label string (e.g. "host", "order"). Resolved from [label_id] at decode time via the legacy seed mapping. Caller-visible string; the registry-stored [label_id] is the source-of-truth identifier.

label_id: LabelId

Authoritative label identifier resolved through LabelRegistry.

flags: u8

out_edge_count: u32

in_edge_count: u32

page_id: u32

Page ID where this node is stored

slot: u16

Slot index within the page

table_ref: Option<TableRef>

Optional reference to a table row (for unified queries)

vector_ref: Option<(String, u64)>

Optional reference to a vector embedding (collection name, vector_id)

Implementations

impl StoredNode

pub fn encode(&self) -> Vec<u8>

Encode node to bytes in v2 format (label_id replaces node_type).

pub fn decode(data: &[u8], page_id: u32, slot: u16) -> Option<Self>

Decode node from bytes (v2 format). For v1 records use [decode_v1].

pub fn decode_v1(data: &[u8], page_id: u32, slot: u16) -> Option<Self>

Decode a v1 (legacy) node record. The caller must supply a LabelRegistry seeded via LabelRegistry::with_legacy_seed so the legacy node_type discriminant maps to the correct reserved LabelId.

pub fn encoded_size(&self) -> usize

Calculate encoded size

pub fn link_to_row(&mut self, table_id: u16, row_id: u64)

Link this node to a table row

pub fn unlink_from_row(&mut self)

Unlink from table row

pub fn link_to_vector(&mut self, collection: String, vector_id: u64)

Link this node to a vector embedding

pub fn unlink_from_vector(&mut self)

Unlink from vector embedding

pub fn is_linked(&self) -> bool

Check if this node is linked to a table row
