Function valid_topological_sorting 

pub fn valid_topological_sorting<I, NodeAttr, ArcAttr, NodeStore, ArcStore>(
    network: &Network<I, NodeAttr, ArcAttr, NodeStore, ArcStore>,
    ordering: &[I],
) -> bool
where
    ArcStore: ArcStorage<I, ArcAttr>,
    NodeStore: NodeStorage<I, NodeAttr>,
    I: Eq + Hash + PartialEq,

Check if a given topological sorting is valid for a network.

Example

use spokes::{Network, algorithms::valid_topological_sorting, ArcStorage};

let mut network: Network<usize, (), ()> = Network::new();
network.add_nodes((0..6).map(|i| (i, ())));
network.add_arcs([
    (5, 0),
    (5, 2),
    (4, 0),
    (4, 1),
    (2, 3),
    (3, 1),
]);

assert!(valid_topological_sorting(&network, &[4, 5, 0, 2, 3, 1]));
