Struct EdgeReference

pub struct EdgeReference<'a, E, Ix = u32>
where
    E: 'a,
{ /* private fields */ }

Reference to a Graph edge.

Implementations

impl<'a, Ix, E> EdgeReference<'a, E, Ix>

where Ix: IndexType,

pub fn weight(&self) -> &'a E

Access the edge’s weight.

NOTE that this method offers a longer lifetime than the trait (unfortunately they don’t match yet).

Trait Implementations

impl<E, Ix> Clone for EdgeReference<'_, E, Ix>

where Ix: IndexType,

fn clone(&self) -> EdgeReference<'_, E, Ix>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, E, Ix> Debug for EdgeReference<'a, E, Ix>

where E: Debug + 'a, Ix: Debug,

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

Formats the value using the given formatter.

impl<Ix, E> EdgeRef for EdgeReference<'_, E, Ix>

where Ix: IndexType,

type NodeId = NodeIndex<Ix>

type EdgeId = EdgeIndex<Ix>

type Weight = E

fn source(&self) -> <EdgeReference<'_, E, Ix> as EdgeRef>::NodeId

The source node of the edge.

fn target(&self) -> <EdgeReference<'_, E, Ix> as EdgeRef>::NodeId

The target node of the edge.

fn weight(&self) -> &E

A reference to the weight of the edge.

fn id(&self) -> <EdgeReference<'_, E, Ix> as EdgeRef>::EdgeId

The edge’s identifier.

impl<E, Ix> PartialEq for EdgeReference<'_, E, Ix>

where Ix: IndexType, E: PartialEq,

fn eq(&self, rhs: &EdgeReference<'_, E, Ix>) -> 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<E, Ix> Copy for EdgeReference<'_, E, Ix>

where Ix: IndexType,
