Trait petgraph::visit::Walker [−] [src]

pub trait Walker<Context> {
    type Item;
    fn walk_next(&mut self, context: Context) -> Option<Self::Item>;

    fn iter(self, context: Context) -> WalkerIter<Self, Context>
    where
        Self: Sized,
        Context: Clone,
    { ... }
}

A walker is a traversal state, but where part of the traversal information is supplied manually to each next call.

This for example allows graph traversals that don't hold a borrow of the graph they are traversing.
