Function spec_order

pub fn spec_order<G>(
    graph: &G,
    vertices: impl Iterator<Item = G::V>,
) -> Vec<GraphElem<G::V, G::E>>
where
    G: FinGraph,
    G::V: Hash,

Arrange some or all elements of a graph in specialization order.

This function is similar to spec_order_all except that the breadth-first search starts only from the given vertices.
