Struct Parent 

pub struct Parent<T> { /* private fields */ }

Storage wrapper for the auto-injected parent field on a struct that declares #[wasm_bindgen(extends = Parent)].

Under the hood this is an Rc<WasmRefCell<T>> so that wasm-bindgen can produce a separately-refcounted parent pointer for JS-side prototype dispatch. Use Parent::borrow / Parent::borrow_mut to access the inner value. You should not need to construct Parent<T> directly outside the child’s constructor; the From<T> impl is the typical way to initialize the injected parent field.

Clone is a cheap Rc clone — both copies point at the same parent data. Debug prints the wrapper plus the inner T (when T: Debug).

Implementations

impl<T> Parent<T>

pub fn new(value: T) -> Self

Wraps a value in a new Parent<T>.

pub fn borrow(&self) -> Ref<'_, T>

Immutably borrows the wrapped value.

Panics (or throws on the wasm target) if the value is currently mutably borrowed.

pub fn borrow_mut(&self) -> RefMut<'_, T>

Mutably borrows the wrapped value.

Panics (or throws on the wasm target) if the value is currently borrowed.

Trait Implementations

impl<T> Clone for Parent<T>

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Parent<T>

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

Formats the value using the given formatter.

impl<T> From<T> for Parent<T>

fn from(value: T) -> Self

Converts to this type from the input type.
