Trait petgraph::visit::VisitMap

pub trait VisitMap<N> {
    fn visit(&mut self, a: N) -> bool;
    fn is_visited(&self, a: &N) -> bool;
}

A mapping for storing the visited status for NodeId N.

Required methods

fn visit(&mut self, a: N) -> bool

Mark a as visited.

Return true if this is the first visit, false otherwise.

fn is_visited(&self, a: &N) -> bool

Return whether a has been visited before.
