Struct Edge 

pub struct Edge {
    pub id: EdgeId,
    pub version: u64,
    pub source: NodeId,
    pub target: NodeId,
    pub edge_type: EdgeType,
    pub properties: PropertyMap,
    pub created_at: i64,
}

A directed edge in the property graph

Edges have:

• A unique ID
• A source node (REQ-GRAPH-007: directed)
• A target node
• An edge type (relationship type)
• Properties (key-value pairs)
• Creation timestamp

Fields

id: EdgeId

Unique identifier for this edge

version: u64

Version for MVCC

source: NodeId

Source node (edge goes FROM this node)

target: NodeId

Target node (edge goes TO this node)

edge_type: EdgeType

Type of relationship (e.g., “KNOWS”, “WORKS_AT”)

properties: PropertyMap

Properties associated with this edge

created_at: i64

Creation timestamp (Unix milliseconds)

Implementations

impl Edge

pub fn new( id: EdgeId, source: NodeId, target: NodeId, edge_type: impl Into<EdgeType>, ) -> Self

Create a new directed edge

pub fn new_with_properties( id: EdgeId, source: NodeId, target: NodeId, edge_type: impl Into<EdgeType>, properties: PropertyMap, ) -> Self

Create a new edge with properties

pub fn set_property( &mut self, key: impl Into<String>, value: impl Into<PropertyValue>, )

Set a property value

pub fn get_property(&self, key: &str) -> Option<&PropertyValue>

Get a property value

pub fn remove_property(&mut self, key: &str) -> Option<PropertyValue>

Remove a property

pub fn has_property(&self, key: &str) -> bool

Check if property exists

pub fn property_count(&self) -> usize

Get number of properties

pub fn connects(&self, node1: NodeId, node2: NodeId) -> bool

Check if this edge connects two specific nodes (in either direction)

pub fn starts_from(&self, node: NodeId) -> bool

Check if this edge goes FROM a specific node

pub fn ends_at(&self, node: NodeId) -> bool

Check if this edge goes TO a specific node

Trait Implementations

impl Clone for Edge

fn clone(&self) -> Edge

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Edge

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Edge

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Edge

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Edge

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Edge

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
