Struct petgraph::csr::EdgeReference

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

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
