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.

Implementations

impl<F, G> EdgeFiltered<G, F> where
    G: IntoEdgeReferences,
    F: Fn(G::EdgeRef) -> bool, 

pub fn from_fn(graph: G, filter: F) -> Self

Create an EdgeFiltered adaptor from the closure filter.
