Struct SkipDuplicates

Source 
pub struct SkipDuplicates<StoreImpl>
where
    StoreImpl: GraphStore,
{ /* private fields */ }
Expand description

A GraphStore wrapper that skips nodes that have already been visited.

This is necessary to avoid repeated work when traversing non-tree graphs (i.e. where a node can have more than one incoming edge).
