Struct ComponentRegistry 

pub struct ComponentRegistry { /* private fields */ }

Registry for storing components with runtime borrow tracking.

The registry tracks which components are currently mutably borrowed to prevent multiple simultaneous mutable borrows (which would be undefined behavior).

Implementations

impl ComponentRegistry

pub fn new() -> Self

pub fn insert(&self, id: Ustr, component: Rc<UnsafeCell<dyn Component>>)

pub fn get(&self, id: &Ustr) -> Option<Rc<UnsafeCell<dyn Component>>>

pub fn remove(&self, id: &Ustr) -> Option<Rc<UnsafeCell<dyn Component>>>

Removes the component with id, returning it when it was registered.

pub fn is_borrowed(&self, id: &Ustr) -> bool

Checks if a component is currently borrowed.
