Struct SubtreeRegistry 

pub struct SubtreeRegistry { /* private fields */ }

A named registry that maps string keys to reusable subtree factories.

Subtrees are stored as closures that produce a fresh BehaviorNode on demand; this avoids shared mutable state while still allowing reuse.

Implementations

impl SubtreeRegistry

pub fn new() -> Self

pub fn register<F>(&mut self, name: &str, factory: F)

where F: Fn() -> BehaviorNode + 'static,

pub fn instantiate(&self, name: &str) -> Option<BehaviorNode>

Instantiate the subtree named name, or None if not registered.

pub fn contains(&self, name: &str) -> bool

pub fn names(&self) -> impl Iterator<Item = &str>
