[−]
[src]
pub struct EdgeReference<'a, E: 'a, Ty, Ix: 'a = DefaultIx> { /* fields omitted */ }
Methods
impl<'a, Ty, E, Ix> EdgeReference<'a, E, Ty, Ix> where
Ty: EdgeType,
[src]
Ty: EdgeType,
pub fn weight(&self) -> &'a E
[src]
Access the edge’s weight.
NOTE that this method offers a longer lifetime than the trait (unfortunately they don't match yet).
