Struct GraphEdge 

pub struct GraphEdge { /* private fields */ }

A property-graph edge model.

Implementations

impl GraphEdge

pub fn new( id: EdgeId, source: VertexId, target: VertexId, label: EdgeLabel, ) -> GraphEdge

Creates a graph edge between two vertices.

pub fn with_property(self, property: GraphProperty) -> GraphEdge

Adds a property.

pub const fn id(&self) -> &EdgeId

Returns the edge identifier.

pub const fn source(&self) -> &VertexId

Returns the source vertex identifier.

pub const fn target(&self) -> &VertexId

Returns the target vertex identifier.

pub const fn label(&self) -> &EdgeLabel

Returns the edge label.

pub fn properties(&self) -> &[GraphProperty]

Returns edge properties.

Trait Implementations

impl Clone for GraphEdge

fn clone(&self) -> GraphEdge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphEdge

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

Formats the value using the given formatter.

impl PartialEq for GraphEdge

fn eq(&self, other: &GraphEdge) -> 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.
