Struct petgraph::visit::EdgeFiltered

pub struct EdgeFiltered<G, F>(pub G, pub F);

An edge-filtering graph adaptor.

The adaptor may filter out edges. The filter implements the trait FilterEdge. Closures of type Fn(G::EdgeRef) -> bool already implement this trait.

The filter may use edge source, target, id, and weight to select whether to include the edge or not.

0: G

1: F
