Struct petgraph::stable_graph::EdgeReference

pub struct EdgeReference<'a, E: 'a, Ix = DefaultIx> { /* fields omitted */ }

Reference to a StableGraph edge.

Methods

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

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

Formats the value using the given formatter.

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

impl<'a, E, Ix: IndexType> PartialEq for EdgeReference<'a, E, Ix> where     E: PartialEq,

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

This method tests for self and other values to be equal, and is used by ==.

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