Struct petgraph::graph::EdgeReference

[+] Show declaration

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

[−] Expand description

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).

fn clone(&self) -> Self[−]

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.
