Struct petgraph::graph::EdgeReference

source · [−]

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

Expand description

Reference to a Graph edge.

Implementations

source

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

source

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).
