Struct petgraph::csr::EdgeReference

pub struct EdgeReference<'a, E: 'a, Ty, Ix: 'a = DefaultIx> {
    index: EdgeIndex,
    source: NodeIndex<Ix>,
    target: NodeIndex<Ix>,
    weight: &'a E,
    ty: PhantomData<Ty>,
}

Fields

index: EdgeIndex

source: NodeIndex<Ix>

target: NodeIndex<Ix>

weight: &'a E

ty: PhantomData<Ty>

Implementations

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

where Ty: EdgeType,

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<'a, E, Ty, Ix: Copy> Clone for EdgeReference<'a, E, Ty, Ix>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, E: Debug + 'a, Ty: Debug, Ix: Debug + 'a> Debug for EdgeReference<'a, E, Ty, Ix>

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

Formats the value using the given formatter.

impl<'a, E, Ty, Ix> EdgeRef for EdgeReference<'a, E, Ty, Ix>

where Ty: EdgeType, Ix: IndexType,

type NodeId = Ix

type EdgeId = usize

type Weight = E

fn source(&self) -> Self::NodeId

The source node of the edge.

fn target(&self) -> Self::NodeId

The target node of the edge.

fn weight(&self) -> &E

A reference to the weight of the edge.

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

The edge’s identifier.
