pub struct NodeRegistry { /* private fields */ }

A catalogue of GraphNode entries keyed by their numeric ID.

Implementations

impl NodeRegistry

pub fn new() -> Self

Creates an empty NodeRegistry.

pub fn add(&mut self, name: impl Into<String>, kind: NodeKind) -> u64

Adds a new node with the given name and kind, assigning a fresh ID. Returns the assigned ID.

pub fn get(&self, id: u64) -> Option<&GraphNode>

Looks up a node by ID.

pub fn get_mut(&mut self, id: u64) -> Option<&mut GraphNode>

Looks up a node by ID mutably.

pub fn find_by_kind(&self, kind: &NodeKind) -> Vec<&GraphNode>

Returns all nodes whose kind matches kind.

pub fn enabled_count(&self) -> usize

Returns the number of currently enabled nodes.

pub fn len(&self) -> usize

Returns the total number of registered nodes.

pub fn is_empty(&self) -> bool

Returns true if no nodes have been registered.

pub fn remove(&mut self, id: u64) -> Option<GraphNode>

Removes a node by ID. Returns the removed node if present.
