Struct NodeId 

pub struct NodeId(/* private fields */);

A graph node’s identity. Content-addressed (the hash of the node’s label and canonical value), so the same entity extracted from different messages converges on one node. Minted SDK- or projector-side.

Implementations

impl NodeId

pub const fn from_u128(value: u128) -> Self

Wrap a raw 128-bit id.

pub const fn as_u128(self) -> u128

The raw 128-bit value.

pub const fn to_bytes(self) -> [u8; 16]

The big-endian 16 bytes (the payload wire form).

pub const fn from_bytes(payload: [u8; 16]) -> Self

An id from its big-endian 16 bytes.

impl NodeId

pub fn content(label: &str, value: &[u8]) -> Self

A content-addressed node id: the stable hash of the entity’s label and canonical value, so the same entity extracted from different records (or upserted by different callers, in any SDK) converges on one node, which is what makes a graph rather than disconnected pairs. The one canonical content_id, so every SDK mints the same id from the same segments (pinned by the golden vector below).
