Function petgraph::algo::is_isomorphic

pub fn is_isomorphic<N, E, Ty, Ix>(
    g0: &Graph<N, E, Ty, Ix>, 
    g1: &Graph<N, E, Ty, Ix>
) -> bool where
    Ty: EdgeType,
    Ix: IndexType, 

Return true if the graphs g0 and g1 are isomorphic.

Using the VF2 algorithm, only matching graph syntactically (graph structure).

The graphs should not be multigraphs.
