Struct NodeHandle 

pub struct NodeHandle { /* private fields */ }

Handle to a node, returned by the node! macro.

Provides ergonomic access to node identity and pin references.

Example

let node_a = node!(graph, (100.0, 150.0), text("Node A"));
let node_b = node!(graph, (300.0, 150.0), text("Node B"));

// Connect first pin of node_a to first pin of node_b
edge!(graph, node_a.pin(0) => node_b.pin(0));

// Access raw node ID if needed
println!("Node A has ID: {}", node_a.id());

Implementations

impl NodeHandle

pub fn new(node_id: usize) -> Self

Creates a new node handle with the given ID.

pub fn pin(&self, pin_id: usize) -> PinReference

Returns a reference to a specific pin on this node.

This is the primary way to reference pins for edge connections.

pub fn id(&self) -> usize

Returns the underlying node ID.

Trait Implementations

impl Clone for NodeHandle

fn clone(&self) -> NodeHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<NodeHandle> for usize

fn from(handle: NodeHandle) -> usize

Converts to this type from the input type.

impl From<usize> for NodeHandle

fn from(node_id: usize) -> Self

Converts to this type from the input type.

impl Hash for NodeHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeHandle

fn eq(&self, other: &NodeHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
