Struct EdgeId 

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

A graph edge’s identity. Content-addressed over its endpoints and type, so the same relationship is one edge however many times it is observed.

Implementations

impl EdgeId

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 EdgeId

pub fn content(from: NodeId, edge_type: &str, to: NodeId) -> Self

A content-addressed edge id over its endpoints and type, so the same relationship observed any number of times is one edge. Idempotent upsert keys off this id.
