Trait IncomingEdgeCount 

pub trait IncomingEdgeCount: TopologyBase {
    // Required method
    fn in_degree(&self, node: Self::ElementId) -> usize;
}

Exact incoming-edge count capability.

Pairs with IncomingGraph for backends that can report in-degree without traversal; does not require incoming traversal support by itself.

Required Methods

fn in_degree(&self, node: Self::ElementId) -> usize

Returns the number of edges entering node.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
