Enum GraphDirection 

pub enum GraphDirection {
    Outgoing,
    Incoming,
    Both,
}

Which way a neighborhood or subgraph walk follows a selected edge.

Every other directed operation follows outgoing edges. A reversed question is asked by swapping the endpoints rather than by changing what an operation means.

Variants

Outgoing

Follow edges away from their source.

Incoming

Follow edges back towards their source.

Both

Follow edges either way. A self-loop reaches the node it starts at, which the walk has already reached.
