Trait KeyedNodeTemplate 

pub trait KeyedNodeTemplate<N, P, K> {
    // Required methods
    fn node_data(&self) -> N;
    fn keyed_ports(&self) -> Vec<(K, P)>;
}

A reusable component whose pins each carry a key — typically an enum variant — declared alongside their data.

This is the keyed sibling of NodeTemplate. It exists to kill positional index bookkeeping: the pin’s identity and its data are stated together in one list, and Graph::instantiate_keyed returns a key → PortId map, so no call site ever refers to a pin by integer position.

#[derive(PartialEq, Eq, Hash, Clone, Copy)]
enum Pin { Anode, Cathode }

struct Diode;
impl KeyedNodeTemplate<&'static str, &'static str, Pin> for Diode {
    fn node_data(&self) -> &'static str { "D" }
    fn keyed_ports(&self) -> Vec<(Pin, &'static str)> {
        vec![(Pin::Anode, "+"), (Pin::Cathode, "-")]
    }
}

Required Methods

fn node_data(&self) -> N

Fresh node data for one instance of this component.

fn keyed_ports(&self) -> Vec<(K, P)>

Fresh (key, port data) pairs in pinout order. The key is what you’ll look up by; the data is the port payload.

Dyn Compatibility

This trait is dyn compatible.

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