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).

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
