Trait EdgeReference

pub trait EdgeReference<'graph, Graph>: Debug
where
    Graph: Graph,
{
    // Required methods
    fn id(&self) -> Graph::EdgeId;
    fn tail(&self) -> Graph::VertexId;
    fn head(&self) -> Graph::VertexId;
    fn weight(&self) -> &Graph::Edge;
    fn project<'reference, T: Project<'reference, <Graph as Graph>::Edge>>(
        &'reference self,
    ) -> Option<T>;
}

A reference to an edge in a graph.

Required Methods

fn id(&self) -> Graph::EdgeId

Returns the identifier of the edge.

fn tail(&self) -> Graph::VertexId

Returns the identifier of the tail vertex of the edge.

fn head(&self) -> Graph::VertexId

Returns the identifier of the head vertex of the edge.

fn weight(&self) -> &Graph::Edge

Returns a reference to the weight of the edge.

fn project<'reference, T: Project<'reference, <Graph as Graph>::Edge>>( &'reference self, ) -> Option<T>

Project the element to a struct representing a single labelled edge.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
